I worked with the ground wire,and the hook ups on the guage,and the hook up to the ignition..I ran out of options so i ordered a new sending unit..I hope that is it. I have the wire coming from the sending unit hooked up on the left hand side of the guage as the wiring diagram calls for,and then I have the right hand side wire hooked to the Ignition asthe diagram says???Is there another way I could hook up this guge? I am going to re-wire the ground before I install the new sending unit,and check the sending unit before I out it back in the tank,,,Any more Ideas ??? Thanks for the help. Gaff...oh ya, I tried the sending unit before I installed it and when I moved the float up and down nothing happened, then I checked the oms and it read 0...
