Using an Ultra HP carb centerdrain bowl makes it easy to plumb in a super-cooled fuel system. The fuel lines (yellow arrows) lead from the fuel bowl drains. These are connected to a tee junction (white arrow) that is in turn fitted into a junction block. Leading from this junction block is a fuel line (green arrow) that is connected to the suction side of a small electric fuel pump with a capacity of 30 gallons per hour.
