1992 D250 Fuel Gauge quit

[topfuelr473]

I have a 1992 D250 Cummins and the other day the fuel gauge quit reading. At first I thought maybe it was the sending unit but this truck has 2 tanks and the aux. tank does not read either. I looked underneath where the valve is for the 2 tanks and everything looks to be good there. Has anybody encountered this situation? Thanks for your time.

Start checking your grounds. I’m betting you have a bad connection somewhere.

Everything else works just the fuel gauge stopped working. Would there be a special ground for that? I'll check the power down by the solenoid for the dual tanks. Thank You for the help.

Check your dash gauge by shorting the fuel sending unit wire,the gauge should go to full.Also the changeover switch.
