Adding a Fuel Bladder -- grounding

This was an old post and I am confused what the question is exactly. What are you transferring gas to and from?

I am transferring gasoline from an ATL bladder with a 12v Fill-Rite pump. There are 3 wires with alligator clips , Black, Green and Red. Power ground and bonding.

connect the green clip to a grounded part of the boat. Connect it first. Grounded parts could be a negative buss or as mentioned a negative battery post. The purpose of the ground is to discharge any static buildup in the transfer pump. The green connection is not bonding. It is in theory earth ground as opposed to the black conductor which is technically the neutral conductor.
It may be desirable to touch the nozzle tip (if metal) to the metal of the fuel fill fitting to discharge any static buildup in the transfer hose to nozzle plumbing.

Note that if you have shore power and it is connected, your Ground is electrically different than your neutral.

So green and black can go to the same negative battery post?

Cool thanks for the help. I do not have shore power. I am 2 hours away from my boat and I’m not sure if I have a grounding stud but if not I will connect to the negative battery post.
