Grounding a Fuel Tank

[brunowren]

I read on a previous post about grounding a fuel tank? Not to be stupin but how? <br /><br />I took my tank out and the only wires hooked to it where the sending unit wires... <br /><br />Should there be something else?

Re: Grounding a Fuel Tank

My boat has a wire(ground) that goes from the the sending unit to the back of the filler to get rid of static. I have that others also run a wire to a grounding bar or negative post on the battery.

Re: Grounding a Fuel Tank

You were probably reading about an aluminum fuel tank. Plastic fuel tanks don't need to be grounded. If your fuel tank is a non-conductive material, you're ok. If it's metal there should be a 1/4-inch tab for a quick-connector welded to your tank somewhere, or something like that to connect a ground wire.

my old tank (aluminum) - one wire from fuel fill to a tab onto the tank. next wire from toab on tank to neg side of battery.<br /><br />i didnt want to have to ground again after i found pits on the inside of my tank. so my solution was:<br /><br />new tank (black plastic) - i also bought a new fuel fill set up that is all black plastic with red plastic cap and requires no grounding.<br /><br />i guess after all my research i came to the conclusion if you have metal it has to be grounded. i also learned some technical jargan, since it is not connected to the ground it is called bonding.<br /><br />here are the sites i used.<br /><br /> http://www.uscgboating.org/alerts/alertsview.aspx?id=27 <br /><br /> http://www.uscgboating.org/safety/boatbuilder/fuel/183-572.htm

Re: Grounding a Fuel Tank

Thanks! Yea it is a aluminum tank but there are no tabs on it .. except on the new sending unit I just bought...<br /><br />Could I run 2 wires from that, one to the gauge and one to the neg terminal ? ?

Re: Grounding a Fuel Tank

kinda thinking out loud here. but if your sending unit has a spike in it from the ground going through it. would you fry it so you cant get a reading to the guage.<br /><br />if i was to do it. i would take it to a place and have a small tab welded to it. mine was only a 1x1 thin guaged metal with a hole in the middle to attach the wires to.

Fry ! Ok I guess I can run a wire from one of the screw holes that attaches it to the floor since these are aluminum tabs that are welded to the tank! That should work! Right ?

Re: Grounding a Fuel Tank

Did the tank have 2 wires on it before? Because the sender usually only has 1 wire going back to the gauge and the other one is the ground.

Re: Grounding a Fuel Tank

take a continuity meter/multi-meter.. go from the ground sending unit post to anywhere on the tank.. if'n it reads,, your good.. <br /><br />just one wire to the sending unit is all that's needed for the tank..

Re: Grounding a Fuel Tank

Yea it had the center post of the sending unit with a yellow wire and on one of the screws holding the sending unit in the tank their was a black wire that went to a ground on the trim pump! <br /><br />So I guess that would be my ground huh ? Duh ! <br /><br />LOL ! Thanks
