Ok I have 2005 ish 150. When we run it at high rpm for a while, then stop and fish a while it loses fuel prime. The bulb is soft and after you pump it it will crank back up after a few seconds. I replaced the bulb and the gas is all new and clean. It runs great at all speeds and doesnt do this all the time. Pretty odd. Thoughts?

Change the female fitting at the fuel tank, sucking in air...

Actually the VST tank holds enough fuel to start the engine so I doubt its a hose problem. Make sure the VST tank on the side of the engine isn't leaking fuel for some reason. Also check the fuel pressure on the VST tank.
