A faulty resistor box or worn float arm on your 2003-2004 Mustang Mach 1 or SVT Cobra can turn a simple fill-up into guesswork, leaving you with an inaccurate fuel gauge or a dead-in-the-water fuel system. The All Classic Parts sending unit installs directly onto the fuel pump module assembly to restore accurate, factory-correct fuel level readings on DOHC applications running the dual in-tank fuel pump setup.
Targets the two most common module failures. This part replaces both the resistor box and the float arm in a single service, addressing the root causes of erratic or unresponsive fuel gauge behavior without replacing the entire pump assembly.
Factory-matched electrical signal. The built-in float arm communicates with the fuel gauge exactly as the OEM unit did, so the gauge reads accurately from empty to full with no calibration adjustments or wiring modifications needed.
Correct application for the DOHC dual pump platform. The 2003-2004 Mach 1 and SVT Cobra use a dual in-tank fuel pump assembly specific to the DOHC engine configuration. This sending unit is engineered to that assembly, ensuring proper fitment and function without adaptation.
