In tank electrical connections?
I need to extend the fuel pump and level sensor wires inside my tank..
Question is.. is heat shrink OK with petrol, and are crimp connectors OK with petrol.
Which way is the best option?

I don't know but if I was going to use heat shrink in a petrol tank I for one would test some in petrol beforehand for several days ??

Very few materials are petrol proof esp now that Ethonol is being added (Bio fuel) and the ratio set to increase from 5% to 15%. Best way is to solder
on new wires both ends no breaks. I have taken varios materials and left them in a jar of petrol outside, after a week examin the contents. If it
survives a week without obvious degredation then it is probably petrol resistant but with bio fuel most bets are off, all bio fuel requires special
materials. I would not use a crimp in a tank.
Petrol is not worth messing with.

All OEM connections are crimped, even those within the tank. The last place you want a wire fatiguing and then breaking due to solder wicking is in
your fuel tank.

I was extremely worried about any electrical connections in the tank but in the end i soldered andcovered with a small piece of heat shrink, my theory
being a small piece of heatshrink would not go thru the filter and i could pick it off it i had to.
The electricians at work told me if its that dangerous why do all manufacturers do it ? their theory was nothing will spark in petrol and even if
above the fuel there is no air O2 present to allow an explosion to occur ?
On my first start up i still had the extinguisher ready but standing over the potential bomb and not taking cover could have been a mistake !
I think it just feels more dodgy than it is

Although you never asked this, but I seem to remember that ptfe wire was the sort to use in a fuel tank.
