    Iv got a line that goes to a Y splits to each carb idk where it needs to go.
    And on the motor behind the starter there 2 hose nipples one for the puls line and what is the other one for this y line I have?

    Something is not right here

    The front carb only gets the one 8mm fuel line in from the fuel filter assembly.Then the rear carb is fed from the front carb

    The 2 pulse lines are 1)Rear one is for the solenoid that activates the rave valves 2) Front one to the fuel pump on the front carby which pumps fuel to the carbsClick image for larger version.

    They don't show it on the diagram but on the carbs where the diagram cover is there's a line connected there on each carb.

    Yes it does number
    1) is the single only fuel line that feeds the pump it is 8mm ,
    2) is the return line 6mm that comes out of the T fitting then returns back to the tank next to the idle stop screw. The fitting marked pulse goes to the front crankcase fitting under the starter

    this ski has a seliond set up that just like the one on the other side of the ski that runs the rave valves and works off the throttle position changing vacuum? found this Update manual made just for this ski with this year..

    Well there you go you learn something new everyday, never knew the 97.5 had this arrangement.

    The fuel system is still the same as above
