Engine/Transmission (1994 - 1998) Wavy fuel gauge

[Got Smoke?]

Anybody know if replacing a fuel sending unit would fix and extremely wavy fuel gauge?



My last truck it wasn't as noticable or annoying but however on my current truck a good tap of the brakes will send the needle flying if the tank is anything less than full.

A sending unit going bad can do a number of crazy things, including what you are describing. Replacing the sending unit should take care of it... .
