    Frequently asked questions

    Do you sell fuel tank straps and sending units?
    Yes — when listed in our catalog under fuel system or related categories.
    How do I match fuel system parts to my engine?
    Use engine model, OEM part numbers, and VIN data. High-pressure common-rail components must match exact spec.
    Are fuel parts non-returnable after install?
    Fuel-contaminated or installed components may be restricted — see returns policy.
