    I bought a 2011 Nissan/Hatsu 20hp 4 stroke awhile back. The manual doesn't specify the fuel line size. The fuel will be in the bow so its going to have a 20' run or so. 3/8" or 5/16"? I'm leaning toward 5/16", the type 1 3/8" is huge.

    5/16 will be fine but I run ethanol free and ONLY get 3 years out of the "Best"? line available :mad: :eek: :mad:

    5/16 is PlENTY
    3/8 will feed 400 hp from that length
