Actually, make sure there is no chance of it ending up on wrong battery terminal by color coding/wire length. I run all my grounds to a separate ground terminal block away from batts.

Very good! Thanks for your help mark. The battery is closer, it's actually under a molded in back bench seat and not in the engine compartment. thanks again!

Jim

ok, That's what I was getting at. why do you do that? I assume just out of convenience but is it more unsafe to ground directly to the battery if you wire it to the correct(negative-black) terminal?

I can just as easily run the wire back to the dash. Could I ground it directly to the fuel gauge ground?

Yes, but what you don't want is any chance of having somebody connect 12v+ someday instead of 12v-, especially if it has another ground as well.

BOOM.

That's what Mark was getting at.

I would hit a ground NOWHERE NEAR 12v+

Ok I understand the concern. So where is the grounding block in the engine compartment usually located? Thanks

I kinda wonder if that's not the reason my fuel sender didn't have a ground wire to begin with?

Yes u can ground back to guage, I group all my grounds away from battery to keep things tidy/avoid acid corrosion of terminals/avoid incorrect connection of grounds to positive, Since batteries are the only electrical connections that are undone periodically.

Thanks mark
