  • little too no fuel in VST ?

    OX 66
    2 stroke
    250 HP
    2001
    Engine is new too me ,
    filter changes , idling multiple days few minutes each day , water pumping strong , then all of sudden sputtered , starving for fuel , died , That was last week
    Rechecked W/F separator gasket and primary filter , Good

    Turning key switch 1 turn I feel pumps working , Pushed in on shrader valve , no fuel came out , Curious , opened drain plug VST , , EMPTY
    Fuel pumps working , but no fuel coming up
    How much fuel should be stored in VST tank ? ,
    If pumps working its not electrical ,
    3 Low pressure fuel pumps
    pumps fuel into high pressure pumps located within VST tank ( previous owner just had VST rebuilt ) saw invoice

    What should I be searching for ??

    your help appreciated greatly

    Bad anti siphon valve,, low fuel tank. Faulty fuel line as in pinched close or loose and sucking air. CK fuel system by using primer bulb (facing upwards) and watch fuel filter on engine
