Question about Cars & Trucks
Purple and thin black wire
Posted on May 02, 2015
If your fuel guage is not working check the ground wire on top of.fuel tank. Most of.the.time the sending unit in the tank is bad....not good news there. Most part stores sell the unit with a new fuel pump only. Cost you some green backs there. More bad news... the fuel tank has to droped to replace it... i my self find it is easyer to unbolt the bed of the truck and raise it up on blocks. Then you can see your wire loom and check your wires with the fuel tank in place.

Testimonial: "Thanks, will check out.."
you are probably correct. there are two contacts on the level sensor that wear out, which gives you the fluctuating gauge.
