Well we have solved this fueleing and starting issue.
when we cut off the back the original fuel tank and pump had to go,
So we got the tank seen in the pics above shown with its pump.
took it to an event and it ran but would periodically struggle which we thought was the pump not keeping up, upon further thought and info from this forum it was the opposite of too much fuel from the pump which would then stall the pump and lead to an almost stall of the engine.
so we fitted a pressure regulator.
unfortunately the damage was done already and the plugs were covered in crud from running rich.
so now with the regulator tuned to 50 psi and the plugs cleaned she runs sweet again.
We have replaced the rear +2" Heavy Duty springs with stock springs as the +2" isnt needed with the weight reduction and the stock springs are softer so should articulate better.
Today we will disconect the rear anti roll bar.
make sure to repair the battery clamp.
think about capstans for the recovery straps.
