Keep your fuel gauge reading accurately with the Agility Auto Parts Fuel Tank Sending Unit 4017228, a drop-in replacement for the 1977-1978 Ford Mustang II in L4-2.3L, V6-2.8L, and V8-5.0L applications. The sending unit uses a tank-mounted float and sender that tracks the fuel level and signals the dash gauge, so a stuck, erratic, or dead fuel gauge is a common sign the original may need replacing.

Frequently Asked Questions

What does this fuel tank sending unit do?

It uses a tank-mounted float and sender to track the fuel level and signal your dash fuel gauge, giving you an accurate reading of how much fuel is in the tank.

Does this fit my vehicle?

It is a drop-in replacement for the 1977-1978 Ford Mustang II with the L4-2.3L, V6-2.8L, or V8-5.0L engine. Confirm your specifics in the Buyer's Guide tab.

Is a fuel pump included?

No. The catalog lists Fuel Pump Included: No, so this is the sending unit only. Reuse or source a pump separately if your application requires one.

What are the inlet and outlet sizes?

The inlet is a 0.250 in butt-flare attachment and the outlet is a 0.3125 in butt-flare attachment.

My fuel gauge reads erratically — will this fix it?

A stuck, erratic, or dead gauge is a common sign the sending unit may be failing. If a faulty original sender is the cause, this unit replaces it; diagnose the gauge and wiring first.
