My guage floats all over so Today I got under the car and pulled the connectors around the tank.The first was next to a black box with a fuel line running out of it and the other 3 were next to that.All I did was disconnect each one and spray the plugs with deoxit and plug them back in.I know the guage SHOULD be reading less than 1/2 as I have OVER 200 miles on the tank right now but now reads above full? Whats up with that? Also,what is that black plastic box under the tank with the fuel line coming out of it?Which plug is the guage? The one in the box with 2 wire?

 

Hello; you most definatly have a poor ground.I dont know what your colour code on those wires are but if i remember correctly you have power to your pump,ground to pump and a wire to the guage ( usually purple ). check to see if the guage is grounded properly at the tank. Good Luck Sean
