Hey everyone. I have been chasing a grounding problem for some time on my 67. I have installed a few senders hoping to resolve the issue. When I pull the sender out of the tank and just connect the ground it works the dash fine. As soon as I install it the needle pegs at full. Some how its grounding. Any assistance would be great.. My one thought.. Is the tank supposed to be isolated from the chassis via the tar strips and the rubber insulators on the straps? Please help.. Thanks everyone.
