fuel gauge reads wrong

There is a ground strap that needs to be installed. It clips on the fuel tube at the tank and onto the line going front. It makes a connection where the rubber hose dosen't.

I eliminated my factory fuel line on my tank and put a sump in it. The gauge no longer worked. What I did was drilled a hole in the very corner lip of the tank and ran a ground strap to the body. It now works fine.

If you do not have the factory clip on ground strap. yo will have to ground the tank. Do not rely on the tank installation straps . Mine did not make a good ground through them. Steve
