massive reconfiguration time again.

Above it with no support, I would look into routing it around the same way the factory line is run, and using braided steel lines.
But that's my point I don't want the gas running along the motor and getting all heat soaked and then going up into the carburetors. I like it exactly the way it is. It's a hard line just connected with a 3-inch piece of rubber hose at each end. It is an electric pump I can just shut it off if there's any trouble.
