Where is the sender on the fuel gauge?
Checking the wiring on the back of the fuel gauge may require going underneath the dashboard, removing the instrument panel, or removing the gauge from the dashboard. The sender unit is located on the fuel tank and, in many vehicles, it is accessible under the back seat or trunk.
How does the fuel tank sending unit work?
Here’s how the fuel gauge works: The fuel gage circuit consists of the sending unit in the fuel tank, the gauge in the dash, and the wiring and dash wiring (or circuit board) between them. As with most sensors, the tank sending unit is simply a variable resistor.
How does the gas gauge work on a Ford F150?
The gauge with a needle operates by a surrounding heating coil, which links to bimetallic strip and needle movement, indicating that the tank is full. If something happens like fuel drainage, then the float drop resulting in the production of electrical current. It sends to the gauge and gives the signal of fuel level.
What does it mean when your fuel gauge reads Full?
Disconnect the wire that connects the fuel gauge to the sender unit, then turn the vehicle on. If the fuel gauge reads full, this indicates a problem with the sender unit or the in-tank mechanism.

What kind of fuel gauge does Ford use?
From the Autometer website: The short sweep electric fuel gauge manufactured by Auto Meter for the Ford 73-10ohm range is calibrated for the original Ford factory supplied, non-linear, fuel level sender design.
What is resistance range of fuel tank sending unit?
The fuel tank sending units used on all Ford products up through 1986 have a resistance range of approximately 8-12 ohms full and 70-73 ohms empty. (I tested my factory 25-gallon in-frame auxiliary tank’s sending unit, however, and got readings of 20Ω full and 85Ω empty.)
