View Full Version : Fuel Filter question

05-10-2014, 11:41 AM
Hello all,

I'm in the middle of 'summerizing' my LSV as well as tackle a laundry list of mods. I'm wanting to change out the fuel filter and I noticed mine is a 'Mercury Mercruiser PN 35-864572' inline type filter. Since this boat is recently "new to me" I'm not sure when the filter was last replaced and if this is the correct filter? Does that sound like the correct filter for an Assault 325?
Also, I see some guys going to a fuel/water separator type filter.....thoughts?

1/2" inlet and 1/2" outlet filter from any auto parts store.

I have always gotten mine from ski dim but now that I know I can get from an auto parts store in a pinch that's awesome!

I used a WIX 33299. That's what was in the boat and what I replaced it with. O'Reilly's auto about $12

Awesome, thanks for the replys guys! I'm liking the $10-12 down the road option vs the $40-50 mercruiser one. I was hoping something from Napa would work but this being my first boat I just wanted to be sure.
