ok, both the sending unit and the pump are grounded to the tank and then that ground goes to the engine compartment where it is plugged into a wire housing, block or what ever its called. the pump wire has three splices in it and then it runs up to the wire "housing" in the engine compartment, through the fire wall and into another wire "housing" then the fuse box is on top of that.
I think i read somewhere that the ground should be on the frame and not the tank itself
