  • 1988 prov150 fuel line size

    Do any of you all know what size are the fuel lines that tie the carburetors together are? I tried some 3/8 and just seems to big. I`m thinking 5/16 but before I go buy some just seeing if anybody has any input.

    Thanks

    You will find out it is metric.

    Buy the ones from Yamaha for your motor they are molded so they will not kink making the bends to connect everything together, but are not cheap

      Yam 40 I saw that. It would be 78 dollars to replace all of the lines. When I saw that I about died. I bought the one for the bottom carb which has the most bend in it. Thinking now that some regular fuel line would work as the rest are not as bad with the bends.
