Gents,

Does anyone have link to fuel pump replacement for the M25XP? I'll need to go to a local auto store. I'm needing the GPH and PSI specs. I found this one and I think it works. https://www.napaonline.com/en/p/BK_6101075?cid=paidsearch_shopping_dcoe_google&store=31162&campaign=GSC-Fuel-Emissions&campaign_id=10951730297&adgroup_id=113117085528&adtype=pla&gclsrc=aw.ds&gad_source=1

I'm on anchor in a bad spot waiting for sea tow so if you don't actually now what fuel filter would replace it than don't respond.

Thanks,

Ryan

The Facet models on my list will work but are not the ONLY ones.

The demands of our engines are very forgiving as to the fuel pump and many many Facets Gold series will work - many are 32 gph which is way overkill but doesn't matter. Min 4-5 psi is fine.

Thanks. I was able to get the first one ordered to Napa. Arrives Monday, so I'll be hanging out till then. The current one looks pretty old so was probably on last leg. Just crossed the Gulf from Destin to Tampa without issue. Anchored outside Gulfport Marina for now.

Guys : Just remember that the fuel tank on the C34 is higher than the engine and the fuel will syphon down to the engine!!!

Have you checked the screen in the bottom of the pump? possibly it's blocked.

Ryan : Just make sure that your electric fuel pump is plumbed in the fuel line after the Racor filter. That way the fuel pump get filtered fuel and you never have to check the screens on the fuel pump!!

How a diesel mechanic explained the reason for that sequence is -- If the pump is first in line, it can emulsify H2O molecules into the diesel, then they do not get separated in the Racor and can be transmitted to the injectors.  :cry4`

His logic made sense to me! :thumb:
