Fuel filter for 98 mercruiser MPI

[Bakes5]

Ok...does anyone know the official fuel water separator for a 98 mercruiser mpi (2200v with the 5.7)

I think I have it narrowed down to the teleflex 18-7944 or the 18-7844. The 7844 is 21 microns and the 7944 is 10 microns.

I currently have a 25 micron quicksilver one and it runs great. I've always just swapped out what was on it but have seen a few different answers now that I tried to look it up. I get all sorta of different answers depending on where I look. Anyone know the official answer?

Thanks

I would recommend the 10 micron. They are actually made for fuel injected engines. The 25 is more for carb engines
