I don’t recall the source anymore, but when I was selecting fuel filters the info I had suggested 40 microns max for fuel injection systems.

Summit has another filter that looks nearly identical that goes down to 35 microns, with a stainless steel mesh screen. It isn't rated for as much flow, but it still borders on the ridiculously high for our application. I'm going to install one of those after the pumps, and one of the PRM-81794 before. The PRM will insure the fuels clean and dry, and the other will catch any pieces that come loose from the pump. I feel very comfortable with that design.
I may also install one of the glass filter that go inline with the hose, putting it forward of the firewall. They're only $10 and it would give me a decent preflight check that nothing has gone horribly wrong upstream while I wasn't looking. Is that sound reasoning?
