Question about 1981 Chevrolet Corvette
Why does my fuel gauge read way over full when I turn on the key in my 1981 Corvette?
Posted by Anonymous on
Hi there. If the fuel gauge is the only one acting up, its probably a loose or corroded wire on top of the gas tank where the fuel pump sets in. It could also be a loose wire on the back of the gauge, which is easier to get to so you could always check that first by popping off the dash pannel and pulling out the instrument cluster and looking for a broke wire on the back of the fuel gauge. But if I had to bet I would guess its on the other end by the fuel pump. Worse case sinario, maybe a bad sending unit.

I changed the fuel pump on my 1997 chevy pu. The fuel gauge reads full all of the time. It only has 1/4 of a tank.

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

this is caused by a defective gas gage sending unit, the sending unit is part of the fuel pump module inside the gas tank, the gas tank must be removed to replace the fuel pump module that also contains the sending unit.
