OK, one more trek into this endlessly talked about subject. This is on the '51 Burb with a 12 to 6 vlt step down in the line to the E side of gauge.My guage moves from E to F about a quarter inch when ignition switch is activated with tank full. The tank is well grounded to frame as I checked it from the fuel line at outlet nipple and at the sending unit mount plate. What other tests can be performed without dropping tank and pulling sender (which is what I dread doing) I have a spare gauge, multitester etc.
