i have a 90 f30 that is stuck on the rear tank the fuse is good and with a light tester when i switch the switch the current chabges to a different wire same at the valve i could only get a current on two wires though? any idea

 

I got the same exact problem on my truck. I plan on pullin it this evening to clean it up. Everything I have had to fix on my truck so far has just been rusted shut. I'll let you know how it goes.

 

thanks i have power to 2 of the wires on the valve 1 with the switch on front and 1 with the switch on rear but the other 3 or 4 wires got nothing and the guage doesent switch back and forth and i know know if the tank vavlve is switching i can hear anything
