Ok so for the most part we know that the baldwin PF7977 was the best fuel filter for the stock fuel system which is at 5 microns. But now it seems afe has been able to release a 3 micron drop in fuel filter. AFE Power 44-ff010 Proguard D2 Fuel Fluid Filter Meets 3 Micron Level for sale online | eBay I looked at afes website and didn't see any micron rating. I even called their customer support and the guy I spoke to (michael) said it is indeed a 3 micron rated fuel filter. So it looks like for those keeping the stock fuel system, afe is the way to go. Pro GUARD HD Fuel Filter. I am curious to see anyone who has ran the bald and afe and if they have had any issues with either.

that afe filter has been around for years. It's riddled with bad reviews of fitment issues as well. I would love to see some data from afe on it though which I doubt they'd provide.

Like do they not publicly list it as a 3 micron filter because technically it's a 1% effective at 3 microns filter? lol.

for example, unless something changed the Baldwin data is:

1-2 Micron Nominal
5 Micron to absolute at a 98.75% efficiency

IIRC that afe is not a water separator type filter.

Fitment as in to tall? To wide? To small? Doesn’t seal right? I’m curious.
