Fuel Gauge?

My fuel gauge is jumping around like crazy when i drive my truck, and when i shut the truck off the gauge drops way past E. Think its power or ground problems i should check for?

Re: Fuel Gauge?

An excellent tech/troubleshooting article on testing a fuel gauge.

I used it last month on my 69 GMC and it pointed right to the problem.
