Gas bulb problems 99 75hp Merc

[Buck12]

I have a 99 75hp tiller Merc that often dies at slow speed or trolling. The gas bulb seems to lose pressure and if I pump it the engine will continue to run. This seems to happen every 20-30 minutes. I did change squeeze pumps but then that pump lost pressure when accelerating. Anyone got a solution?

Maybe bad gas lines allowing pressure to ecscape?

You may wnat to check your fuel pump.. The gaskets get old and need replacement

Thanks for the suggestions. I'll see how they work.

You might want to check for vacuum leaks from the fuel pump all the way in to the gas tank. if it's sucking a little air, the fuel pump is losing it's prime.
