When I wrote this it was meant to say to ground the blue wire....at the sending unit. Pull it off the sending unit then ground it there. If the gauge pegs that will tell you that everything from the sending unit to the gauge is fine and that there's a problem with the sending unit.

Could be a sunk float, bad internal ground, rheostat arm inside the unit fell off (all of which actually happened to various units of mine). Also, may have bad rivet connections on the unit etc, etc, etc.

Well I will remove the ground at the gauge and see what happens . . Would have been easier at the tank for sure . .
Drive it like you stole it . . . And they're CHASING you!

Yeah sorry about that. I was hoping when I wrote the above it would have lead you to the tank. Just for further clarification the blue wire on/at the sending unit is power pulsating 5v.

This sentence confuses me, did you mean to say Blue wire?
