My fuel sender was broken by the PO. I ordered a used sender from Vines Automotive with a 6-month warranty. The old one was broken due to a dent in the fuel tank right where the sender was, and the new one would not fit. This was remidied by pounding out the dent with a piece of wood.

The new sender is in now, but it shows the wrong level on the dash. Does anyone have any idea why this could happen?
