Now that we know the wire from the tank is sending current, the next thing to check, is whether the original gauge/instruments have been changed, or maybe the sending unit is having problems.
Have you pulled the sending unit up out of the tank to see
if the float/rod/etc. is OK?-Bob
It's also possible that with a turbo, since the air/fuel must
be readjusted, that you are burning more gas than you once did.
