Here's an article:

That's fine after the pump but not on suction side of an electric fuel pump.
You need the biggest filter you can fit. The Aero filter is 60 sq inches of filter & 100 microns. That installs between the tank & the electric pump. The 10 micron can go in the engine compartment or on the motor.

Edit: I found the article I was looking for.
