    lol, I have read somewhere it was 30lph and the triple outlet was 35. I have read other places the stock was 35lph so I am just a little confused

    I would imagine the single outlet put out 35lph x 1 outlet or 35 lph total. Triple outlet must output 35 lph x 3 or 105 lph total output.....?

    But the hex (pentagon) pump DF62-702 is a two outlet. The one I have seen recommended, and bought was the Round Triple outlet 35 lph DF52-92.....

    From K447 post......:

    "Why you want a triple fuel pump upgrade on your Fuji engine Polaris
    Lots of information has been posted on Green Hulk Polaris forums regarding the triple outlet fuel pump upgrade.

    Bottom line, the stock Fuji fuel pump, when operating in 100% good condition, can supply enough fuel to keep the engine from running lean.

    The problem is when these single outlet fuel pumps age, they become less effective, and cannot supply enough fuel flow to keep piston temperatures below self-destruct levels.

    At WOT (Wide Open Throttle), if the fuel pump is weak, the engine doesn't get quite enough fuel flow, the MAG (front) carb starves the most, and that piston ends up with a hole burned right through the top of the piston.

    You can rebuild the original fuel pump, and that will be JUST enough fuel flow to keep the engine happy. For a few dollars more, you can install a new, high flow triple outlet fuel pump, and be sure your engine will never be starved for fuel.

    These improved fuel pumps do NOT increase gas consumption, they simply supply enough fuel pressure to keep the carburetors operating properly."
