    1994 polaris triple carb question

    Is the pulse line from the crankcase to the carb, go to the 1 outlet on the back of the carb that sticks out.? or is the other one on the perimeter of the pump? i know 3 of the four are fuel outs to the carbs. where do you run the 3 fuel lines to the carbs?. i took off the caps on 2 of the carbs and used them. and the last line i put on the lil round thing where the original fuel line went. is that wrong? do i have to put a cap on that 1 line running to the carb? i didnt touch the upper rail. looks like im getting flooded. it ran fine earlier in the day with the original pump. now just the plugs gets soaked. i have good compression 130. replaced both main and reserve lines. cut each to exact length. also installed new filter.it's clean. half tank gas, plenty of oil. change lines to fuel separotor and fuel lines . the very long lines from the tank i kept. they are in good shape. helllllllllllllllllllllp installing this thing.going out tomm morning hopefully to test n run it. last good day of the year.

    The pulse line goes to the back of the pump, not the carbs. Unless you have the pro mikuni sbn 44's.
    Heres a diagram of the fuel line routing... you are adding the triple outlet pump right?

    Not trying to high jack your thread but it is relevant.. Can the triple outlet fuel pump be put in the same location as the old one?????

    I seen some of the members on here drill holes thru the ribs of the boat and mount it in the bottom of the boat is there any reason for this???? Cya Slick

    Yes it could.

    Bringing the fuel pump closer to the pulse fitting (engine) shortens the hose length. Shorter hose = stronger signal for better pump performance.

    It also helps to "prime" the fuel pump as fuel flows down with gravity easier than pushing up to the pump.

    NOTE: that the fuel pump MUST be installed above the pulse fitting. This prevents any water or excess fuel from settling in the vacuum hose and damaging the pump diaphragm.

    It's usually a quick fix, what's the issue you're having?
