    Fuel tank vent check valve??

    IM HAVING A PROBLEM ON MY GP760, WHEN I GET TO ABOUT A HALF OF TANK OF FUEL I GET ALOT OF STALLING AT LOW AND HIGH SPEEDS. TODAY IT GOT SO BAD I COULDENT GET IT STARTED WAS WITH THE PRIME IT RUNS FOR A SECOND AND THEN DIES. WHEN I OPENED THE FUEL CAP THE TANK HAD ALOT OF PRESSURE (GOOD OR BAD????) MORE THEN NORMAL, ONCE I RELEAVED THE PRESSURE I WENT TO START THE SKI AND IT RAN FINE, IS THERE ANYTHING ELSE THAT VENTS THE TANK THAT COULD BE BLOCKED OR STUCK CAUSING THIS. VENT FILTER?????(CAN I GET RID OF THIS)

    3 psi is around what the valve holds in the tank to help the fuel system

    boats.net is in florida you can also use a pressure tester to verify the valve
    they usually fail in the open position but anything is possible
    you can ride without it but order a new one if it is the culprit

    I guessed a year but that won't change anything
    the vent is supposed to let air in and keep 3 psi or so trapped in the tank
    so it is free flow one direction only and pops off over pressure in the other
    make sure there are no kinks in the lines
