You have a vacuum leak. Replace the bulb and the hose and the two end fittings. You're evidently losing prime.

C'mon guys. You cannot, by definition, have a vacuum leak. If there is nothing (a vacuum) it cannot be leaking. Like - what happens to it after it has leaked out? Where does it go? Will it burn? Can you compress it?
That's right, you can't because it isn't really anything. So remember it is always a leak of something else, usually air. Try to be just a tad accurate in your posts and you might be believed.

i took the seat out to get to the tank and have acccess to all the fittings. I tightensd all connections and put a new bulb on the fuel line. The boat has 2 tanks and a valve swith to where you can turn fuel on to one tank and then switch to the other tank.So thereare 2 seperate lines going to this valve switch and then one from the switch to the motor. This morning I took it out and it ran good and never quit and fished for about 15--20 minutes and started it up and ran for 1/4 mile and it missed and quit and the bulb had nothing in it. We pumped the bulb up and it started and ran good????? ?????

Why can`t you have a vacuum leak? If a system is designed to operate on a specific amount of vacuum and there is in-leakage of any fluid, say air at atmospheric pressure, isn`t this a vacuum leak?

It seems to me that the only point of your post was to be obnoxious and it appears that your mission was accomplished.

I forgot to mention, the bulb doesn't deflate when gas is not in it.
