Frequently Asked Questions
How do I find the right diesel part?
Search by the PAI part number or OEM reference. If you only know the engine, use the engine finder. Compare the listing with your engine model and serial number before ordering. For applicable Cummins engines, check the Control Parts List (CPL) too.
What does one pack include?
Check the selling unit under Product Details. For example, a pack of six contains six units, and a quantity of two packs contains twelve. The displayed price covers one complete selling unit.
When do I see shipping and tax?
When online checkout is available, enter your U.S. delivery address and select Review shipping & total. Review the shipping quote and any pending tax before paying. If a payment link is available, it appears on the quote page.
How do I check the warranty?
Open the product’s Description tab and look under Warranty. Coverage depends on the part and its application. For a claim, have your order number, PAI part number, and a description of the issue ready.
Shipping and Delivery
Enter your U.S. delivery address for a shipping quote. The quote shows the available service, freight charge, and whether tax is still pending. Contact parts support before ordering if you need liftgate service, pallet freight, or a delivery option the site does not offer.
Check the recipient, delivery address, and phone number before paying. We send tracking when shipment is confirmed. If we cannot ship as promised, we will contact you with the available options, including cancellation and a refund for unshipped merchandise where applicable.
Returns
Request approval before sending a part back. Have your order number, PAI part number, quantity, and reason for return ready. Wait for return instructions and the correct shipping address before sending anything.
Keep the packaging and contact us promptly if the shipment is damaged, incomplete, or contains the wrong item. For a suspected defect, see the warranty information on the product page. For other returns, ask us to confirm eligibility, any return shipping costs, and the refund method before sending the part.
Contact

Cookies & Browser Storage
Cart and quote access
When checkout is available, your browser can keep your cart and a shortcut to your latest quote between visits. The production store sets a separate secure cookie when you request or recover a quote. It lets you reopen a bookmarked quote in the same browser for up to seven days.
To remove the saved cart and quote access from this browser, clear this site’s data in your browser settings. A submitted quote or order stays on file. If you need help reopening one, contact parts support with your quote reference.
Product images and payment
Your browser requests product photos from PAI’s image service. When you choose to pay, you leave the storefront for Square’s hosted checkout. Square’s own notices apply to cookies and browser storage on its payment page.
Terms of Sale
A shipping quote shows the parts, quantities, and delivery terms available at the time. Review the selling unit on each listing. The displayed part price covers one selling unit, which may be a pack or pair. The final quote shows freight and applicable tax before payment.
Use the Square link on an active quote to pay. If a quote expires or availability changes, contact us before sending another payment. We verify payment before releasing the order for fulfillment. If we cannot supply the order as agreed, we will contact you about the available options.
