Hi David,

Just modded the sender for my build to fit it into the tank. My first question is....

How have you bolted/bonded the pump and sender unit to the tank?

and secondly.....

Surely if you earth the tank to the body when fuel causes a path of least resistance between the tank and the live wire in the tank the pump and/or sender will stop working and probably blow a fuse??

I was thinking about this this morning after reading up on fitting a metal fuel tank. Surely the tank needs to be isolated from the body altogether?

Confused!

Edit: I must be miss understanding something about vehicle electrics as surely even if the tank wasn't earth bonded to the chassis the pump and senders positive and return would short when wetted by fuel. I remember having the same thoughts when I replaced an in tank fuel pump and my old car.

Edit!!!!

Oh petrol in non conductive ! Well that explains a lot!! haha! I thought all liquids conducted electricity! Doh!
