  Motorcraft™ Fuel Cap, Cap Assembly Fuel Tank Filler

• Description:

  This genuine Ford Motorcraft fuel tank filler cap seals the fuel filler neck on the 2005 through 2008 Ford Mustang, closing the fuel system against vapor loss and maintaining the pressure and vacuum balance the evaporative emissions system needs to operate correctly. Ford and Motorcraft catalog it as the fuel tank cap, a non locking threaded cap with a calibrated pressure and vacuum relief valve and a captive tether that keeps the cap attached to the filler neck so it cannot be lost during refueling. The internal seal and relief valve are wear items, and the rubber gasket hardens while the ratcheting mechanism wears, so a failing or loose cap is one of the most common causes of an illuminated check engine light with an evaporative emissions leak code, along with a fuel smell around the filler area and a poor seal that fails the ratchet click test. Fitting a correct sealing cap restores the closed evaporative loop and typically clears the small leak fault once the drive cycle completes. This cap uses the correct thread, seal, and relief calibration for the Mustang filler neck and replaces the original equipment cap. Hand tighten until it ratchets several clicks to confirm a proper seal. Cataloged as Motorcraft FC-1032 and Ford part number 6R3Z-9030-A.
