A couple weeks ago my boat broke down, the bulb wouldnt stay hard and i flooded it to high hell. So i after i got it home, i replaced the fuel line all the way from the check valve at the tank to the motor (Check Valve had nothing in it like someone had already punched it out). Replaced the bulb with a new Mercury Bulb, and rebuilt the pulse pump with a merc kit. Ran great all day last Saturday. Today it ran great but every once in a while at full throttle it would just run out of gas. Had to stop 4-5 times and pump the bulb, then it would run great again. Sometimes it stays primed and other times it doesnt. Any thoughts????
