    sl750 tripple output fuel pump

    Im in the process of changing to a tripple output fuel pump. I know I should remove the auto-cock from the fuel system but what should I do to the pulse line that runs from the auto-cock to the carb for the pto cylinder? Thanks....

    There are two pulse lines on the stock setup for the fuel pump. The first one goes from the fuel pump to the crank case (1/4" fuel line) , and the second goes to from the auto-cock to the carb for the PTO cylinder (1/8" clear plastic). The new fuel pump that I have only has one pulse line input. I was going to run the pulse line from the crankcase to the fuel pump and remove the auto-cock which whould leave the second pulse line with nowhere to connect. Should I just cap this off at the carb ??? I can post some pics tonight if needed......Thanks

    On my sl750, I have two clear tubes in my hull. They seem to be this 8th inch size. I found where one went, it went to the mfd under the shaft.

    The other, I have no clue. I think this post may be what I was looking for.
    I think it runs to the front of the ski to a vent, but not sure. Where exactly does this hose connect in the fuel system?

    The vent tube for the battery if it has one?

    Plug that sucker off at the carbs but use a damn good cap as you don't want issues with it later.

    I use the MBZ diesel block off plug.
