[Jtobe81]

Fuel Gauge reads past full. I tested the gauge it is good and new. new sending unit and tested with the gauge. works normal when hooked up with leads. tested the circuit board with leads to the sending unit and gauge works normal. checked ground.

I am lost think i have done everything.

3 o'clock means you have an open circuit, like a broken wire, unplugged, etc. 9 o'clock means it's grounded somewhere.

yeah i did the trouble shooting steps that i found on you tube from lmc, where you test the gauge using a battery and leads. the gauge and sending unit work normal when i have them hooked up with leads to a 12v battery. That was my last thought maybe a broken wire. looks like the wire is pink/red from the sending unit. trying to follow it back but cant find out where it goes into the cab.
