Remove the screws that hold the sending unit to the tank and take it out. Next, remove the three wires on the back of the old gauge. One wire goes to the center pin on the tank sending unit, one goes to ground, and the third connects to a 12-volt source, normally the ignition switch. Remove the fuel gauge.
Can a fuel sending unit be fixed?
Sometimes the fix can be as simple as changing an instrument cluster fuse. For more information on how to fix a gas gauge that is not working, check out our Resource Center article on how to test and replace a fuel gauge and sending unit.
