Ford 420 industrial fuel sending unit

Russell Moore · Mar 26, 2016

We had to pull the cowl off the fuel tank on our 420 industrial yesterday
After we cleaned everything up and put it back together I cant seem to figure out where the wire going to the fuel tank sending unit has gone
Does anyone have a wire diagram they could send me or any information would be a help
Thanks

It's pretty simple The wire for the sender should go from the back of the fuel gauge directly to the sender. The other side of the sender is grounded through the mounting bracket to the tank. The resistance of the sender varies as the float arm moves up and down.
