Tim -

Not sure about the EMPTY reading with a bad ground on the gauge. That ground serves a different purpose than the ground at the sending unit. I bench tested my gauge and forgot to ground the gauge. I remember that it didn't read right when I briefly connected to power, just don't remember what it read. (Senior moment). Not saying you're right or wrong. Just saying that I'm not sure.

RE: my "50%" reading - -
My fuel gauge is a repro. It read 50% in the box. I bench tested it with the repro sending unit -- sending unit and gauge properly grounded. Seems to work OK, just does not go back to EMPTY when off, like the original ones did. I called The Truck Shop and was told mid-reading when off is OK. I noticed that pics in the Truck Shop catalog and other suppliers show the needle at various locations other than EMPTY.

Jimmi - please update us when you find the problem.
