Question: How do you fix an inaccurate fuel gauge?

How do you fix a fluctuating fuel gauge?

You can connect the sending unit to the gauge for testing before dropping it in the tank, just provide a ground with a alligator clip lead to the body of the vehicle (not near the open fuel tank). You can then move the float up and down and make sure the gauge is going from full to empty while moving the float.

Why is my gas gauge not working properly?

A faulty fuel gauge sender may cause the gauge to suddenly change positions, or give an inaccurate reading. The gauge may appear to be at three quarters, and then only a few minutes later will change to half full, or vice versa the gauge may appear to be full, only to have the gauge climb higher a short while later.
