Payment Policy

The purpose of this policy is to discuss the forms of payments accepted.

Credit, Debit, Purchase cards are referred to as "Credit Cards" as they operate in similar ways in regard to use with this store. Most purchases on this website will be made with Credit Cards sequentially against invoices generated as orders during checkout on the store. Unique Diesel accepts payments via Credit Cards (except: American Express) for smaller invoice purchases and optionally offers the ability to use manual traditional payment methods such as Money Orders, Cashiers Checks, Wire Transfers, and Cash in US Dollars for larger purchases. For certain high value items a credit card courtesy fee may be optionally selected with the product at order, this selection must match the payment type being used during checkout. If an item that requires a credit card courtesy fee is purchased and the selection for the courtesy fee is not selected and the item is fully checked out on the store using a card the order will be incomplete. To complete the order, customer service will require the customer to remit the courtesy fee separately, incurring an additional amount for handling the correction.

There are several thresholds in force that limit total amounts accepted via credit cards and concerning minimal order value for use of manual traditional payments. For this additional information used towards your purchase please review the following page that will require you to use your store customer login account to fully view. This page also outlines the manual order process and guides how this occurs (login required).



This online store has the ability to securely store a card on file for use with a purchase and future purchases. This ability to save card information for use can only be done by the customer. Customer service may request that a customer save card information in their account on the store to facilitate additions and changes to an invoice order. The customer grants permission to use the card stored by the customer through these communications with customer service. When a card payment is required for use to pay for changes to an order, the card must be saved and used within the store, external payment methods using a card are not accepted.

Cancel Order Policy

Cancel Order Policy - Whole Order

Occasionally a customer will request a whole order cancellation for a number of reasons not exclusive to shipping rate and time, quantity available and others. Orders made on the store that are incomplete and customer service is unable to resolve the deficiency with the customer are also subject to a whole order cancellation. Whole order cancellations apply that do not contain Build To Order items and only when no parts of an order has been provided to a shipping carrier. For a whole order cancellation a 20% order cancellation fee applies for USA Domestic orders and a 25% fee for International that will be deduced from the total refund amount issued. In the event that an order has been prepared for shipment (packaged, item marked shipped in store with tracking number) the refund will be less a 35% product unpacking and restocking fee instead of the cancellation fee. This policy seeks to recover lost credit card processing fees both in taking and refunding the amounts, and for time and resources wasted accounting for the cancellation. Resulting customer limitations apply, reference Account Terminations.

Cancel Order Policy - Build to Order

Products that are Build to Order are custom and running long block engines, re-manufactured injection pump and injectors, and custom and tested new injection pumps and injectors. Items that are Build to Order are items that have to be customized, assembled, produced in order to fulfill a specific order and are not kept in stock matching all the criteria of an order. These items will have a posted delay in shipping for the time necessary to produce the ordered item known as a lead-time. Shortly after an order is received containing Build to Order items, resources are used to complete the order including ordering items or replacement items to complete the order. Cancellation of items listed Build to Order can only be cancelled within 5-days of placing the order and will incur a 50% order cancellation fee.

Special order items may be considered non-cancellable and potential refund is at the sole discretion of Unique Diesel. A classification of an order as a special order is also at the discretion of Unique Diesel, and potentially associated with a lead time or normally stocked.

Cancel Order Policy - Back Orders

Orders placed on items on the store that allow back-order (items not in stock but to be ordered) will incur a 35% stocking fee if a back order is requested cancelled.

Cancel Order Policy - Partial Order Item Removal

For some odd circumstance in which items placed on an order are requested removed from an order prior to shipping (no tracking number generated). They may be requested removed, amount refunded will be less 15% of amount in credit after item is removed from invoice. In circumstances where the item being removed is approximately 50% or more of the dimensions and weight of order, a partial refund on the shipping will be remitted, also less 15% of the refund. Situations where the item's shipping impact does not account for 50% or more, no shipping refund will be issued. Refunds on shipping are completely up to Unique Diesel to decide upon, decisions made are final.

Shipping Policy

Shipping Policy - Handling Time

Shipping handling time is measured in standard business days Monday-Friday and excludes all US federal holidays or any posted business closure on the website. For ground parcel shipments these orders will ship within 2-3 business days. For parcel shipments using the an express or air service these orders will ship the following business day for orders containing less than 15 individual products, larger orders are subject to 2-3 business days handling time. Domestic truck freight and air freight shipments will occur within 5-business days of order for in-stock products only. Separate orders placed within the shipping and handling window for fulfillment will not be combined, even at the request of the customer. To do this affects the process of fulfillment and could cause errors in shipping from an alternative method specified.

Shipping Policy - Ship Order Complete and Split Shipments

Orders placed that contain items with mixed stocking and availability statuses will ship when all items are able to ship at the same time. Mixed stocking and availability is when some items are in stock and some items are available for purchase with a Back Order or Custom and are made on the same order invoice. Shipping estimates on the website are provided based on total combined items on the shipment occurring at the same time. A customer requested split shipment is possible for orders held due to a back ordered item or custom item, customer service can quote and collect payment for additional expenses required. Requests to split shipments to a different address than on invoice are prohibited. Mixed orders that contain local stock and drop ship stock will be automatically split into separate shipments for tracking purposes at no additional costs.

Shipping Policy - Selected Carrier Preference

Selecting a shipping carrier from available methods during checkout is indicating a preference to use the carrier and acceptance of the estimated shipping rate to deliver your order. Unique Diesel reserves the right to change the order preferred carrier method between other comparable carriers and similar service levels. This right is reserved due to inconsistencies between service providers in coverage in all areas for the rates that are estimated by the live shipping calculator within the store. To streamline order fulfillment we will substitute another carrier to one whose rates align with the amounts collected during checkout where possible to prevent additional charges to the customer or potential order cancellation. If a change in service level type (express to ground shipment) becomes necessary we will contact the customer to confirm and negotiate this change.

Shipping Policy - Carrier Performance

We cannot guarantee when an order will arrive. Consider any shipping or transit time offered to you by this site or other service as an estimate. We do not offer refunds on shipping costs based on carrier performance. As an example we will not entertain claims with carriers over late deliveries when the service is overnight or express. We encourage you to order in a timely fashion to avoid delays caused by shipping or product availability.

Shipping Policy - Parcel and Freight Forwarding

Orders placed assume direct delivery to the customer. When a customer utilizes a parcel or freight forwarder this is typically for exports out of the USA. Unique Diesel is not responsible for loss or damage for packages delivered to or through forwarders, use at your own risk.

Shipping Policy - Parcel Loss

For situations involving lost or extremely delayed deliveries as indicated by tracking number, the following process applies. For USPS Customer must report the undelivered item to us to initiate the process only on items that have not been delivered after 15 Days (Priority Mail) or 7 Days (Express Mail) from shipment date. In general, other shipping services by UPS or Fedex the soonest we can investigate lost or delayed shipment is 2x (twice) the amount of business days that the service would normally take.

We are unable to process a claim on shipments that are reported as stolen from a delivery location when the tracking on the item reflects a proper delivery. It it outside of our control the security of a delivery location and will not entertain claims for packages stolen from delivery locations. Choose a trusted or secure location for delivery of your items.

For situations involving carrier damage the damage must be reported via customer service email within 15-days of the receipt of parcels as indicated by tracking. The complete damaged package (box and all contents) must be retained and customer must participate in any carrier insurance procedures and requests by Unique Diesel towards a claim including use of online websites and providing digital images of damage.

For an undelivered or carrier damaged item, a replacement cannot be provided until the claim against the item(s) is settled. After confirmation that we have started the claim, you can wait until settled and receive the replacement, or you can order a second replacement (duplicate shipment). On a lost or delayed shipment, in the event the originally lost item is delivered after it's replacement has been shipped or received, please request return shipping label from us to return this un-opened package within 5-business days of delivery. Following this process allows us to be able to keep warranty on the replacement ordered items on a wait for claim settlement option, or to process a full refund on orders where a duplicate order is placed instead of waiting on claim settlement.

Return Policy - Unauthorized Returns

C.O.R.E stands for Cash On Return Exchange, in current times it means it's a charge applied to a purchase that will be credited when the used item is returned. Customer must identify the core shipment by providing their name and order number from the store, many cores require completing a core information form included with the replacement item. All cores must be returned to Unique Diesel by the term duration indicated on the product option (may be 30 days or more, indicated on invoice) duration starts after the tracking confirms receipt of the item you purchased. Unique Diesel reserves the right to offer a pro-rated return amount for condition of items returned by core criteria, or refuse refund on cores in non-rebuildable condition.

Rev. 1-7-2026
Right To Refuse Service Policy

Unique Diesel values the "Golden Rule" in dealing with people and expects the same of customers.

Unfortunately, a small percentage of customers don't share this value; the following information applies.

Unique Diesel reserves the right to refuse service to anyone. Reasons for refusal of services is being
rude, confrontational, using obscene and derogatory language, breaking policy, and committing fraud. Engaging in rude, confrontational, obscene, and derogatory communications is in violation of the Common Courtesy policy and is seen as personal abuse against any agent of Unique Diesel. Execution of a right to refuse service is in the form of a customer ban when applicable and requires no notice. Once a business or individual has had their customer account disabled as the result of a customer ban, or has been told that they will not be provided services by Unique Diesel and any division this is permanent. Creating duplicate accounts on the store to bypass a customer ban is trespassing, use of a duplicate account to make a purchase and caught prior to shipping will be refunded based on Order Cancel policy and trespass information turned over to law enforcement. Successful attempts to circumvent a customer ban by purchases by others etc. will void all warranty service and product guarantees explicitly and is fraud. Purchases intentionally disputed through Credit Card companies will also result in permanent loss of services from Unique Diesel. Posting negative feedback publicly about products and services by Unique Diesel will result in no future business with the source customer or individual. Making legal threats of intentions of involving an attorney, or filing of lawsuits or letters from attorneys will immediately forfeit customer privileges. Communication at the mention of legal issues will cease except through certified letter.

"If a customer and business cannot settle conflict themselves directly, they need not be doing business."

Rev. 7-14-2026
Account Terminations

This website requires account registration in order to make purchases. Account access is a privilege whose eligibility depends on adhering to policy. Unique Diesel reserves the right to disable an active account for any reason found to be in opposition of policy, notably; Common Courtesy, Right to Refuse Service, and Disputes. Disabling of an account is a penalty and tool to enforce the Right to Refuse Service.

Account Terminations - Order Refunds

When a purchase is made it is treated as an agreement to fully purchase, a request to cancel an order is a breach of that agreement. Total order cancellations, and returns for refunds may suspend future purchase eligibility through account termination. When efforts are utilized towards a sale that ends up in a refund, it is always a negative outcome, for many reasons. Order cancellations and returns for refunds are the result of customer expectations that are not in alignment with our purpose, so future business is not welcome.

Account Terminations - Store Misuse

Several protections and safeguards are in place on the store to prevent a check out that is incomplete, and therefor cannot be filled. Although these safeguards are in place there have been situations where they have been circumvented by misuse of the store. Examples of misuse leading to incomplete orders are providing incomplete, incorrect, phone numbers and or shipping and billing addresses. Misuse of the store could lead to orders that the store doesn't provide a shipping amount, or orders that cannot be shipped by carriers requiring a real phone number. This leads to customer service having to reach out to customers to remedy which is counter-productive to the store. In situations where customer service is able to retrieve information to correct an honest mistake, it can be remedied. In situations where it is obvious that steps were made to circumvent protections ending in an order that cannot be fulfilled the order will be cancelled less any order cancellation fee and account will be disabled.

Creating orders on the store requiring manual payment and not making the payment, necessitating cancellation of the order will not be tolerated. This is misuse of the store and resources and complicates inventory controls. Adding items to a cart and going through the entire checkout process constitutes a contract and accepted invoice. This accepts terms of pricing and store policy. Forcing us to cancel these orders will result in loss of store privileges and exercising the right to refuse future service.

Attempting to checkout using a card resulting in three (3) consecutive card declines will result in a store account suspension. It is the responsibility of the cardholder to provide complete and accurate card security details for processing. Card declines result from inaccurate information provided during checkout, limitations on card due to insufficient funds or purchase restrictions, failure to provide additional authentication required by bank at time of transaction, or a cardholder bank related error. When a store customer account is suspended a login to the store to make a purchase is not possible. Contact customer service to request information about specific card declines and lift the suspension. In the event that a account is re-activated after being suspended and an additional three (3) consecutive declines occurs again without a successful purchase the account will be suspended with penalty. Customers are limited to six (6) consecutive card declines before account suspension is categorized as an account termination. Accounts terminated for exceeding six (6) consecutive card declines are subject to special considerations towards regaining account access including a potential service fee. Unique Diesel reserves the right to consider special circumstances, including the value of items to be purchased when deciding whether or not to enable account access.


Rev. 8-27-2026
Credit Card Disputes

Customers are required to communicate and consult with Unique Diesel Customer Service for any issue regarding financial transactions including but not limited to any refund, cancellations, changes, and over charges. Card companies require customers to communicate and work with a business before escalating to a claim. Cardholder disputes filed with credit card companies known as a "charge back" against payment transactions is fraud when claims are made that are in opposition to any posted store policy “uniquediesel.com/policy” terms, warranty “uniquediesel.com/warranty” terms, checkout invoice terms and conditions, and product descriptions. Claims made by cardholders in opposition to terms accepted at time of purchase and found on this web store will be contested and defended. The cost of replying to and providing documentation for disputing an original claim is hereby understood to be a minimum of 300 dollars. Unique Diesel will seek restitution for all costs associated with defending claims, billing notices, reasonable attorney fees, court fees, and process serving. Defensive actions against claims will occur regardless of decisions made by a card network, processor, or issuing bank. All card dispute claim customers are reported to a global card fraud database as permitted by the Privacy Policy.
