      Trying to buy used or fabricate a fuel line for this Outboard – but the way it connects with correct copper tube size and compression nut is confusing me. I looked at OD 1/4 and 3/8 and neither seemed correct. Any help locating a decent used fuel line or info on tubing and compression nut size would be great.

        There is 5/16″ line as well, if you’re looking for something
        in-between.

         

        Prepare to be boarded!
