Fuel Filters

[MoonRiver]

I have a 1996 330 DA with 200hour 5.7L 350s (Bluewaters). Currently the engines are setup with NAPA 3225's fuel filters as the remotes and QS 35-802893Q01 on the engine mount.

Does this sound correct 12 micron NAPA 3225 (remote) and 25 micron QS on the engine?

Looking for help determining fuel filter replacement type, micron, and GPH rating.

Flip them around. Larger micron should be the first one after the tank.

10 mic is MORE than adequate. OE, I believe, is 25 mic. It's even less important if you have carb's.

So would 25 micron work for both remote and eng mount? Note: I typically only change my fuel filters once a year (50 hrs max) after winter just prior to spring start-up.
