I dont have the boat wired yet so the fuel sending unit is not wired. I understand that I should have the fuel fill grounded to the tank. I read on another site that the tank should then be grounded to the engines ground in this case a 2000 Johnson 150. How do I do that, just splice in to the engines grounding wire? Can I use the grounding tab on the tank for both the fuel fill ground and the ground to the motor. I'm so confused by this wiring stuff, I'm going to have to get a book.
