Restore fuel gauge operation and the factory-style low-fuel warning function on a 1971-1973 Ford Mustang equipped with the low-fuel warning option. This stainless sending unit features a 3/8 inch fuel outlet and an integrated low-level sensor that works with the vehicle’s existing warning indicator, wiring, and electrical components. It is intended for Mustangs originally equipped with, or correctly converted to, a complete low-fuel warning system; the sender alone will not add a working warning light to a standard vehicle.

Classic Mustang Fuel Sending Unit with Low Fuel Sensor | 3/8" Outlet | Stainless

Fits 1971-73 Ford Mustang

Restore accurate fuel-level readings and proper low-fuel warning operation on your 1971-1973 Ford Mustang with this stainless fuel sending unit featuring an integrated low-level sensor. Designed as a direct-fit replacement inside the fuel tank, this unit includes a 3/8 inch fuel outlet and the additional sensor required by Mustangs equipped with a factory-style low-fuel warning system.

Important: This sending unit is intended for 1971-1973 Mustangs that have the factory low-fuel warning option or a complete, compatible conversion using the proper warning indicator, wiring, relay or control components, and electrical connections. The integrated low-level sensor does not create a working warning light by itself. Mustangs equipped only with a standard fuel gauge normally use a sending unit without the low-fuel sensor.


  • 1971-1973 Mustang fitment: Designed for 1971-1973 Ford Mustang fuel tank sending unit applications.

  • For low-fuel warning applications: Intended for Mustangs equipped with the factory-style warning system that includes a low-fuel indicator.

  • Integrated low-level sensor: Provides the tank-side signal used to activate the low-fuel warning circuit when the fuel reaches the system’s trigger level.

  • Operates the standard fuel gauge: Measures the amount of fuel in the tank and sends the corresponding signal to the dashboard fuel gauge.

  • Requires matching warning-system components: Low-fuel warning operation requires the correct indicator, wiring, relay or control components, and related electrical connections to already be installed and functioning.

  • Not required for standard applications: A Mustang with only a conventional fuel gauge and no low-fuel warning circuit normally uses a sender without the additional sensor.

  • 3/8 inch fuel outlet: Provides the fuel supply connection for compatible fuel-system configurations.

  • Direct-fit in-tank installation: Mounts in the factory-style sending unit location inside the fuel tank.

  • Stainless steel construction: Offers a durable replacement for a worn, corroded, leaking, damaged, or inaccurate sending unit.


This stainless fuel sending unit performs two separate functions in a properly equipped 1971-1973 Mustang. It operates the standard dashboard fuel gauge by measuring the amount of fuel in the tank, and its additional low-level sensor supplies the signal used by the vehicle’s low-fuel warning circuit.

When the fuel reaches the sensor’s activation level, the sender works with the Mustang’s existing warning indicator, wiring, relay or control components, and related electrical connections to activate the low-fuel warning. Because this sender is only one component of the system, installing it in a vehicle that does not have the supporting warning-system equipment will not create a functioning low-fuel indicator.

This unit is the correct style to consider when replacing a failed sender in a Mustang originally equipped with the low-fuel warning option, restoring a factory-style warning system, or completing a properly configured conversion. For a vehicle equipped only with the standard dashboard fuel gauge, select the appropriate sending unit without the low-level sensor.

Built from stainless steel and designed to mount inside the fuel tank, this direct-fit replacement is suitable for fuel tank service, inaccurate gauge diagnosis, low-fuel warning repair, electrical restoration, or a complete classic Mustang fuel-system refresh. Before ordering, verify the vehicle’s equipment and confirm that the complete low-fuel warning circuit is present and compatible.


Choose this sending unit for a 1971-1973 Mustang equipped with a factory-style low-fuel warning system. For a standard Mustang without the low-fuel indicator and supporting electrical components, use a conventional sending unit without the low-level sensor.
