Yes. per ABYC and 33 CFR 183. They both should be connected to DC negative.

Pete I am also wondering if the fuel filler should be grounded since it's isolated from the tank by the hose?? I always thought I should do it.

Thanks guys, I was leaning toward the extra wire direct to the engine block.

Sam,
I'd go with the extra wire. There's something that always bothered me about using the copper fuel line as an electrical conductor!  However, the practice was quite common especiaaly for the ground up to the dash when the old copper tubing was used for the mechanical oil pressure gauges.

Sam, would the tank not be grounded by the neutral wire from the sending unit to the ground behind the dash? I'm not sure how these are set up.
I would think that if you need to ground at the block, you could come off with a ground wire from the sending unit and route it to the grounding point on the block. |

My 1955 Chris Craft restoration is almost finished and I'm concerned about fuel tank grounding. Part of the original copper fuel line had to be replaced with rubber and now the fuel tank isn't grounded. Should I run a ground wire from the tank to the engine block, or bridge the part of the copper fuel line that was replaced with rubber with a wire, or what?
