in-tank fuel resistant wiring
I've been playing with my in-tank EFI pump and sender unit, and have managed to accidentally strip a small chunk of insulation off the earth
wire that goes to the sender.
This could potentially short against the positive terminal and presumably result in a rather large explosion. Ouch.
The bit of wire in question has a spade connector at one end and is soldered to the sender board at the other. It would be dead easy to replace. But
do I need to get wire with special fuel-resistent insulation, or is the usual stuff ok?

Pic for your reference. Everything is immersed directly into the fuel. All I want to do is replace the black wire.

I did not think there were live wires in a fuel tank !!!!!!

on my 200sx it had the fuel pump in the tank, which had both +ve and -ve wires going to it.. nothing to worry about

Mines a different design but it also has live wires dipped in the tank. It has made me wonder on a couple of occasions but I am in no danger of
filling the tank with fuel yet.
The white plastic bit towards the bottom has a tightly coiled piece of very fine wire running along the inside of the curve acting as a simple
variable resistor with the float arm.
The tank is so heavy it would probably contain a nuclear explosion anyway.

Apollo 11... heh heh 
So does anyone know if I need special wire?

Possibly its one of those strange situations where there's that much fuel or vapour.. there's vertually no oxygen left to burn?
Would like to think so lol

I guess 12 volts isn't enough to get it going. Think of all the starting problems people have trying to get explosions going in the engine
cylinders. Sometimes even the massive voltages there dont always manage it.

I think I recall that silicone instrument wire is the stuff to use in fuel tanks?
