320 Monsoon noise fuel pump noise

Recommended Posts

I have a slight whine/high pitch noise w/ 99 Response. Comes from back engine area. Noise is consistent. It is not very loud and does not change from idle to in gear, get louder etc...

I was told that these fuel pumps have rep for being noisy??

Other than that boat runs fine.

Any ideas?? Something to worry about?

Fuel pump could be under strain, when is the last time the fuel filters we're changed?

Does it make the noise just at key up (not cranking the engine but letting the fuel pump prime?)

FYI, You have two fuel filters on your boat, one that a lot of people don't know about because it's behind panels

One on the pressure side Fuel Filter Pressure side

One a foot off the main fuel supply in your trunk (you have to remove panels to access Fuel Filter In-Line

hope this helps
