• Description:

  This is a genuine Ford castle nut-and-washer assembly built on the HN3 base hardware that Ford references as a fuel-tank strap nut and support-strap U-nut. It retains the strap that holds the fuel tank against the underbody. Sample applications include the F-250 through F-550 Super Duty with 6.2L, 6.7L and 7.3L engines, plus the Expedition and Navigator; these examples are illustrative rather than a complete fitment list. A strap nut that loosens or corrodes lets the tank shift, producing clunks, chafing and a safety risk at the fuel system. This is a single-use fastener that Ford specifies cannot be reused or reinstalled, so it should be replaced rather than refitted. Because Ford publishes this number as universal service hardware rather than as a single-model part, no finished list of every compatible vehicle is published; confirm the exact application for your vehicle by VIN before ordering. This is a multi-year service part that fits across the model years of the listed Ford applications.

• Notes: Part cannot be reused/reinstalled.
