The only way that I could work out how to do it was to make a custom tank that become one peice (joined over the top of the tailshaft..) - (then there is the safety issue of the tank being punctured in the event of a crash) By not being able to connect the tanks at their lowest point, it would then mean that both sides of the tank would need their own electric pump and inbuilt sump to empty each side of the tank.
It'd have to be set up in a way that one pumps until it a sensor senses that side of the tank is low, and then the other side would cut in.

Its a lot of stuffing around just for double the fuel capacity..

I didn't think about it too much, but there'd be another way to do it...
I am not sure what you are talking about. Just plumb the tanks to a Tee piece before the fuel pump. Unless you are running an aftermarket fuel set up or a later injected motor, you don't need to over think it. Unless of course the WB runs an electric fuel pump, I always thought they were the same as real Holdens and had a mechanical pump on the side of the motor.
