    Default Fuel Line Size

    I have a 1986 442 vin 9 code.
    Someone has replaced the orignal steel fuel line with a rubber one and its making concact with the water pump.
    I want to put a steel fuel line back on to the carb.
    What size is the correct line a 3/8" w/16mm fitting or 5/16"w/14mm fitting ?
