Sending unit ground strap on stainless

In most cases the sending unit is isolated from the rest of the tank by a gasket. It wont matter how much grounding you do to the tank. There needs to be a ground connection at the sending unit mount (normally a clip attached to the output fuel line of the sending unit) and a clip making connection to the ground of the body of the vehicle (also, normally another clip around the fuel line attached to the vehicle). Between the two clips is a short wire of coarse, and the rubber hose that makes the connection from the tank to the fuel line. So this clips and wire are like a ground jumper. If that all makes sense.
