Stainless Fuel Sending Unit with Low Level Sensor | 3/8" Outlet | 1971-73 Mercury Cougar

Restore accurate fuel-level readings and proper low-fuel warning operation on your 1971-1973 Mercury Cougar 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 Cougars equipped with a compatible factory-style low-fuel warning system.

Important: This sending unit is intended for 1971-1973 Mercury Cougars that have a compatible factory-style low-fuel warning option or a complete 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. Cougars equipped only with a standard fuel gauge normally use a sending unit without the low-fuel sensor.

• 1971-1973 Cougar Fitment: Designed for compatible 1971-1973 Mercury Cougar fuel tank sending unit applications.
  
  
• For Low-Fuel Warning Applications: Intended for Cougars equipped with a compatible 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 Cougar 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 Mercury Cougar. 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 compatible low-fuel warning circuit.

When the fuel reaches the sensor’s activation level, the sender works with the Cougar’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 appropriate style to consider when replacing a failed sender in a Cougar originally equipped with a compatible 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 Cougar 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 Mercury Cougar equipped with a compatible factory-style low-fuel warning system. For a standard Cougar without the low-fuel indicator and supporting electrical components, use a conventional sending unit without the low-level sensor.
