They use the Delphi 2 micron fuel / water separator it's meant to be a secondary filter. It will keep your fuel seriously clean. But you can also just go with a baldwin direct replacement which are 10 microns but still around 5% efficient at 5 microns and will give you less restriction in your fuel system.

Baldwin makes some of the best filters since most are microlite filter media, about 80% of there oil filters are and pretty much all automotive direct replacements are that's a 98% Efficient * 12 microns compared to a VIC which is a only 87% efficient at 40 microns (pretty much worthless for protecting your engine for major wear) Almost no protection

The majority of filters are only 95% to 98% efficient * 40 microns since that is the industry standard for OEM. They don't really strive to be any better. Purolator is only 97% * 40 microns.

Most paper air filters are the same, Fram actually makes good air filters their oil filters are worthless junk but the air filters are good. OEM is also perfectly fine.

Most Fleetguards are 96% efficient at 20 microns on their cellulose media, there microglass and stratapore are 5 microns. Wix are also all around 20 microns filters wich do a good job down to 5 microns.

But Baldwin are almost all microlite (cellulose mixed with microglass) with 12 microns rating and filter down to 5 pretty dang well.

Can't go wrong with Fleetguard or Baldwin. They also hold about 4 times more particles before they can get clogged and go into the bypass mode.
