my problem is when i first got the boat (21ft morebas 7200) it had no water fuel seperator it only had a fuel bulb so i added a water fuel seperator after the fuel bulb but before the fuel pump thing is the bulb will not pump fuel anymore (it used to before adding seperator) and i have to put a drop of fuel in the carbs to start it and then its fine for the rest of the day any ideas would be very gratefully received... should i put the filter before the bulb closer to the tank???????

1. you have an air leak in the system somewhere between the fuel pump and the fuel tank.
2. you do not need a primer bulb in a sterndrive, get rid of it.
