In normal conditions the fuel pump does not need a prime. It is a diaphram
pump and is self priming. If you had enough water to get it in the oil you
may have gotten it in the fuel tank too. Take the fuel filter off again and
pour it intoa glass container to see what is in it. Did you have a lot of
water in the original fuel filter? Water can cause problems in your fuel
pump as well. The aresa around the little flapper valves get gummed up.
But it would have had to be longer than this. How do you know you are not
getting gas to the carb? Does it spray from the accelerator pump when you
look down the throat of the carb? Maybe you have water in the carb too.

This past weekend after a heavy rain, I took my boat (2050 bayliner
capri,2000 mercruiser 5.0L 350 engine) from my dock to take it out of
the water. Unfortunately, I did not run my bilge pump nearly long
enough and wound up stalling out in the bay. After getting towed to
the put in and back to the house, I found water in the oil which I
promptly changed, and cranked the engine up. It cranked immediately
and ran for about 10 to 15 seconds, then died again. So I changed the
fuel filter (filled with gas first) and now I cant get fuel to the
carb. Have I lost my prime in the fuel pump, if so, how can I get it
primed back or is the pump gone or am I missing something?
