Restore accurate fuel level readings on your 1999-2004 Mustang SOHC with a direct replacement sending unit that addresses two common failure points at once. A faulty resistor box or a degraded float arm will cause the fuel gauge to read erratically, stick at full or empty, or stop responding entirely. This unit from All Classic Parts installs on the existing fuel pump module assembly to bring both functions back to factory specification without replacing the entire pump.
Replaces the resistor box and float arm together. Rather than hunting down two separate components, this sending unit addresses both the resistor and the float arm in a single service. If either has caused gauge inaccuracy or failure, this replacement returns the system to proper operation.
Built-in float arm signals fuel level like factory. The integrated float arm moves with the fuel surface and sends the correct electrical signal to the gauge cluster, restoring the same behavior the car had when it left the assembly line. No recalibration or gauge tuning is needed after installation.
Direct replacement for OEM part XR3Z-9275-AA. This sending unit matches the original fitment spec, so it installs on the fuel pump module assembly without modification. No splicing, no adapters, and no trimming required.
