    Pulling from rusty memory of swapping the pump in my old '88, I think the pump is grounded via wire coming up and exiting the tank. I think thats because the tank is not a good conductor. I could be wrong, but I'm pretty sure the pump is grounded by wire to the frame...
  3. newyorkin is right. I just changed the fuel pump on my tbi Suburban and there is a ground wire from the pump to the frame.
