Locating Fuel Filters 8.1 L 370 HP

[Tomboy]

Cannot find the port side water separator if there is one. Starboard separator easy to find..
Do these engines have individual fuel filters as well. If so, please help me locate.
Thank you,

I’m not 100% sure there is a separator for the engines. If you follow the line for the starboard side you’ll find that it probably goes to the generator.

I am not sure if the cool fuel system on the 8.1l is just a fuel filter and cooler or if it’s also a fuel/water separator.

my cool fuel system (if that’s what you have) is on the port side of each engine. Near the bottom. Your starboard engine filter will be easy to find if you’re sitting between the engines.

The filters are inside that box. There’s a typical round cartridge filter and a small paper disc beneath that.

My cool fuel units are mounted on the starboard side of each engine.

And yes, the water separator canister filter with disk is located there.

Big help guys. Found the filters/water separators and purchased replacements today. Very expensive!
But then again, when connected to a boat, everything is expensive.

I’ve had good luck with these.
