Aftermarket Fuel Filter Service Life
I'm running an Aeromotive fuel filter housing (relocated of course) and 10 micron fabric element. I only get about 5,000 miles before it loads up and my AFRs start climbing under boost. I have a theory: since I'm running pre-mix oil, the oil saturated fabric traps and holds even more particulate, causing it to load up faster. I'm sure the filter is working well, but wanted to know what service life other members are getting with an aftermarket filter.

Using a fine mesh fuel filter should improve the service life of your injectors, at the cost of added maintenance. I believe most stock filters (as well as aftermarket stainless steel elements) are 100 micron, which is fairly coarse pore size.

This is where I have my filter housing mounted, on the subframe behind the differential.

This fuel filter thing has been bugging me as it is about time to do mine. I went back to an old SX Performance catalog and they have what looks like a great replacement for the factory fuel filter. It is the SX Performance EFI & Carbureted Indicating In-line Fuel Filter. Part of the John Lingenfelter signature series (ohhhhh, pay extra for that). Part# is 41001. They claim it will flow the max that a -10AN line can handle, up to 2000 HP. Less than .15 PSI drop at 200 GPH. Quick and easy to install and remove with choice of 10 micron disposable paper or 60 micron reusable stainless steel filter elements and a pop-up indicating sensor that warns when replacement or cleaning is recommended. It looks like a pretty slick unit. All Mil-Spec anodized 6061 aluminum.
I use one in my fuel system. Actually two of them. I have a smaller diameter one with the metal screen as a prefilter to keep the pump happy, then an SX pump and then the big one you're talking about using a paper filter. It's all bolted to an aluminum plate and mounted to the back of the subframe just behind the differential and in front of the fuel tank. Perfect amount of space. Very nice piece though. Think I paid $60 or so for it with the paper.

I'm actually curious about this as well since I'm replacing the diff bushings and I thought I might as well relocate the fuel filter.
