Grounding a Aluminium petrol tank?

[elv_1986]

I am fitting a pair of new aluminium petrol tanks to my boat. Thinking about the safety side of things, should this tank be grounded? If so, where to, the block?

Has anyone else had any experience with fitting alu petrol tanks that could be of use to me? I dont want to take any chances with petrol!

Thanks,

Louis

All my static discharge lines are grounded to the engine block including my aluminium petrol tank.

Don't forget to ground the metal fittings on the filler and vent hoses too.

Thanks for replying. So I need to get busy with some wire, how are they connected, just a ring connector wherever it will fit on & what thickness of wire should I use?

I have a bare copper wire running down my filler and vent hoses clamped behind the hose clips top and bottom.
I drilled the hose clips at the bottom of each hose at the end of the tail, fitted some 3mm bolts and nuts and the static lines have a ring terminal at each end. Just make up a tidy loom and put the ring terminals under a rocker cover or other small dia bolt You will likely need a longer bolt to do it and still have enough thread left when the rings are underneath.

BSS inspector has passed the setup twice now, so he is happy with it.

Surely if the wire is under the hose clip, then its not grounding the vent as the hose is acting as insulation?

Vent outlet itself does not have to be grounded, only the fill side and parts that could build up static due to fuel washing up and down inc the vent hose clips.

Filler is polymer so that does not need grounding either.
