I know guys who use them and don't have fuel delivery problems, but they only flow 90GPH at 0.5PSI pressure drop, and my pump is supposed to flow 140GPH. My combination isn't anything crazy, but I don't want to use mismatched parts. I think maybe I should get a System1 p/n 200-201408: they say it flows 10GPM (600GPH), and the element is washable.
