I'm going to make this a generic engine question, in hopes of more responses. Besides, I don't think the specific engine info would have much to do with it.

What are possible causes for air build-up in a fuel line/system? Or, what are possible causes for a vacuum being created in a fuel line/system?

I'm bogging and dying after hitting rough water. I've found that when I open the fuel water separator, air is either being pushed out, or sucked in, then fuel flows out, and the engine will start up and carry on like nothing happened.

Let's hear your thoughts, and thanks in advance.
