The fuel is the ground, if none other can be found by the current. This can be also seen in Electric fans on Radiators. If the Radiator is insulated/shock mounted, it has no ground. I've had to replace the goose neck on Hondas as the current flow would eat it away over time.

Need an electrical engineer or equivalent to explain to us if possibly the tank itself with a bit of fuel in it is adequate to ground the few amps that the sending unit is receiving.
