Hello, I'm Tan. Welcome to JustAnswer. I'm reviewing your question and will reply momentarily.

Have you tried running the engine on a different fuel tank? Does the engine run correctly on the other fuel tank?

This will verify if you have a fuel supply issue from the boat side fuel system. Collapsing primer bulb is a fuel restriction.

Have you removed the anti siphon valve and run the engine?

Hi Tan have not run a separate fuel tank. How to I remove the anti siphon valve ?
Customer: replied 1 month ago.
Just checked no anti siphon valve between fuel line ex tank to fuel filter. None from filter to primer bulb
