in tank pump electrical terminal

Making in tank pump setup and need a bulkhead connector to send power to the pump something like this:

Such a simple thing but can't seem to find one online in UK. I might try to make one but don't want to bodge it as I'm not fireproof. Anyone know where to get one?

I am currently having my fuel tank fabricated. I am going to solder on some BS6883 round flex to the pump and bring it out the tank with an ATEX nylon compression gland (see ebay 391051145531). This cable will not allow permiation of the explosive gases and the gland will not allow the products of a fuel tank ignition to exit the tank.

Regular round flex would also do as long as the other end of the flex is not terminated into an enclosed space.

Cheers

That looks like a reasonable option. I should have added that the wire will be going in from the bottom of the tank so submerged in liquid fuel not vapours - not sure if that makes a difference for that gland. I'd still probably prefer a solid stud with appropriate insulators and seals.

Don't think it is very wise having a hole in the bottom of your tank, petrol is very viscous (compared with water) and will leak through anything very easily. You cannot use that gland as a liquid barrier (or should I say, you could - but it would leak).

Why can't you have the cable entry on the top of the tank?

Well its for a bike tank so from the bottom is the only option

Ahhh, yes would look daft with wire hanging out the top!

you dont need to do anything special.....just make sure the connections are bare (not able to trap fuel and bubbles) and not loose....
look at any ford in tank fuel pump
