the gas gauge itself is grounded to the gauge frame when its installed right? Could that be the problem? I just can't see how it could not be. I have an other gas gauge but am trying my best to not have to pull everything apart again to install it. I tried tightening the cap nuts on the gauge and they weren't bad and the metal piece that goes over the studs was also still in place, so I guess I'll dig out the OHM meter and see what that tells me.
