the gauge is really a thermal device.
key off the gauge guts cools and needle goes to 0, does yours?
if yes
then key ON.
we short its gauge input wire (from sender) to ground and the meter heats up and goes to FULL
that is all there is to the easy test. no bath in fuel ever. we test the gauge first.
at the sender wire. anywhere along its length.
if this passes
we look for wire rusted pins on that wire to the tank. no rust allowed. on the wire or the tanks ground.
then wrong sender or bad.
