Restore your 1999-2004 Mustang's fuel system integrity with a direct-fit replacement filler pipe that matches the original routing, mounting points, and dimensions. Corroded or damaged filler pipes cause fuel odors, slow fill times, and failed emissions inspections; this All Classic Parts replacement addresses all three by putting a fresh pipe back in exactly where the factory one left.
Correct mounting and fitment. The upper filler pipe mounts directly to the rear quarter panel opening and connects to the lower filler pipe through the factory connection hose, preserving the original fuel fill path without modifications to the body or fuel system.
A true direct-fit replacement. Built to supersede OEM part number 1R3Z-9034-AA, this pipe fits 1999-2004 Mustang applications and restores function that a corroded, cracked, or missing original pipe cannot deliver. No adapters, no fabrication, and no trimming required.
