Shipping policy

Shipping

We ship nationwide and internationally. Most in-stock items leave our shop within 1–3 business days. Made-to-order and oversized parts may require additional lead time; any special timing will be noted on the product page.

Tracking & Delivery

  • You’ll receive a tracking email as soon as your order ships.
  • We cannot ship to PO Boxes for oversized or freight items.
  • Signature may be required for high-value shipments.

Once an order is marked as delivered by the carrier, it is considered fulfilled. DFIS is not responsible for theft, loss, or misdelivery after delivery confirmation.

Shipping Protection (Optional)

At checkout, customers have the option to purchase Shipping Protection through Route. Route provides coverage for packages that are lost, stolen, or damaged in transit, giving you added peace of mind once your order leaves our facility.

If Shipping Protection is selected at checkout, any shipping-related issues can be resolved through Route’s claims portal. Claims are typically processed quickly and may result in a replacement order or reimbursement depending on the situation.

If Shipping Protection is not selected, Diesel Fuel Injection Service is not responsible for packages that are lost, stolen, or damaged after they have been handed off to the shipping carrier.

Freight & Oversize Items

Large/oversized products (bumpers, racks, etc.) ship via LTL freight.

Please inspect your delivery at arrival. Note any damage on the carrier’s paperwork and take photos before signing—this is required to file a claim.

Residential freight includes curbside delivery; inside delivery/appointments may incur additional fees.

Important: Shipping protection through Route may not apply to freight or oversized shipments. All freight deliveries must be inspected at delivery, and damage must be noted on the carrier’s paperwork.

International Orders

  • Duties, taxes, and import fees are the buyer’s responsibility and are not included at checkout.
  • Some products may have export restrictions or carrier limits.

Order Changes & Cancellations

  • Requests must be made within 24 hours of purchase when possible.
  • Custom or built-to-order items may not be cancellable once production begins.
