Hi Bob, my name is Jason.

They don't paint the insides of the fuel pumps anymore like they used to. Chances are you have a fuel tank issue, possible a bad antisiphon valve if the tank has one. What you want to do is get a portable fuel tank, hook that up to the fuel pump, and run the engine on that. If it runs better on the portable tank then that means you have a problem with the boats tank, and the tank and it fittings and lines will need to be inspected. If no change, then fuel pressure will need to be checked under a load to see if it's actually a fuel pressure problem or not. Does that make sense to you?
