Manufactured to OE specifications, it is engineered to provide accurate fuel level readings while maintaining factory-correct fitment and electrical compatibility.

Installed vertically into the top of the fuel tank, the sender unit uses a float-operated internal mechanism that rises and falls with the fuel level. As the float moves, the sender changes electrical resistance values, transmitting an accurate fuel level signal to the dashboard gauge. Proper operation is essential for reliable fuel level indication and preventing inaccurate readings or unexpected fuel shortages.

This component is ideal for restoration projects, fuel system refurbishment, or replacement of worn or faulty original sender units.

The fuel level sender monitors the fuel level inside the fuel tank and transmits an electrical signal to the dashboard fuel gauge. This allows the driver to accurately monitor remaining fuel while driving.

Function
•  Measures fuel level within the fuel tank
•  Sends electrical signal to dashboard fuel gauge
•  Provides accurate fuel level indication
•  Supports reliable fuel monitoring while driving
•  Maintains compatibility with original gauge system

Over time, fuel level senders can wear internally due to corrosion, fuel contamination, electrical contact deterioration, or float failure. A faulty sender may cause inaccurate fuel readings, erratic gauge movement, or complete fuel gauge failure. Replacing the sender restores reliable fuel level indication and helps prevent unexpected fuel shortages or incorrect gauge readings.

When to replace
•  Inaccurate or fluctuating fuel gauge readings
•  Fuel gauge remains empty or full constantly
•  Intermittent fuel gauge operation
•  Corrosion or damage to sender unit
•  During fuel tank restoration or fuel system servicing
