    Sl 750

    hi I'm rebuilding two SL 750 93 and noticed that the fuel line on both do not have a restrictor and are supposed to be the original lines is that possible or do I have to install one on both of them ?

    Once the engine is rebuilt verify the fuel pressure and you'll know if you need a restrictor or not.
    Being as the boats are 93, I would think the hoses have been replaced at least once. Maybe if they were replaced and no restrictor installed, you have found the problem for your current rebuilds...or are you just freshening the engines?

    Stock 1993 engines would have the brass flow restrictor inside the return fuel line, about an inch from the carb.

    If your return fuel lines don't have the retrictor, and they are the stock 1993 carbs, then you need to install the retrictor. You can find info on making your own in the Fuji links from my signature.

    Edit: Apparently I may be incorrect regarding the 1993 engines.
    I will defer to the Fuji guys on this.
