Long Range Petrol tank access issue

Truthfully, I think by the time you have all of your double redundancy devices in place, you will have twice the joins, wiring seals and equipment to go wrong.

And you are damn right about that.
Nobody knows it better than you do.
And I ain't kidding.
I've already experienced a fair bit of it myself.

BTW, I am big believer in sealing the wires from water/dust/air ingress, since I've had this troll.
If you've seen the pictures above, you know the connectors to the tank was not good with all the crud getting in between them.
