    Dont make it difficult for yourself. If theres any fittings already on the engine it is likely it will be that size but 3/8 --1/2 inch is ample.

    Actually,there is nothing on anything. The motor came without the connector. The other stuff (yes I have a filter/seperator) is waiting for me to pick the size barbs I choose.
    The only rngine connector I found was a 1/4" barb. I ordered a primer bulb to match. Not big enough?

    out uf the rigging manual it states 5/16 fuel line for this engine and my rule of thumb is when in question use 3/8 for 90hp and up
