SHIPPING POLICY
USA SHIPPING:
Depending on the products you order, you can select shipping options by USPS, UPS, FedEX, and DHL. Please contact us if you have a preference for shipping.Â
INTERNATIONAL SHIPPING:
We highly recommend contacting us by phone before placing an international or Canadian order: (801) 901-0667. International shipping costs are calculated during checkout. If your country isn't listed, please contact us.
RETURN POLICIES
GENERAL RETURN POLICY:
Please review the installation guide or video before purchasing, and confirm the pressure and return port locations for your engine. We're happy to provide guidance if needed. Returns are not accepted for buyer’s remorse or if the kit doesn’t match your engine model, so please double-check compatibility before ordering. If you encounter any issues, contact us — we’re committed to finding a solution.
DAMAGED PRODUCT RETURNS:
All products are inspected before shipping. If your product arrives damaged, please report it with photos within 7 business days of delivery. Only unused, damaged items in their original condition are eligible for replacement or refund. If a product is confirmed to be defective or damaged, you can choose between a replacement or full refund after inspection.
OTHER REFUND POLICIES:
In rare cases where a product qualifies for a return (outside of damage on arrival and within 30 days of delivery), a refund will be issued minus return shipping costs and the Shopify transaction fee (2.4%-2.5% + 30¢). Although we *may* offer free shipping during promotions, the original shipping cost will also be deducted from your refund.
Your satisfaction is important to us! If you have any questions or need assistance, please contact us at support@InsaneDiesel.com.
