OK...you asked. Not going to debate this one either .....but.....micron rating has absolutely nothing to due with flow capabilities when discussing fluids with the viscosity levels of fuel.

Micron rating with filters is referring to particulate size its capable of trapping.....and with fuel the smaller the number the better......and before the pump....no true racing quality level of electric fuel pump will make debris.

Not looking for a rumble....only trying to help. If I wasn't kicked back on vacation right now....I would probably not have bothered as I know this will stir the key board warriors






This post really tells me you do not know fuel pump plumbing. Ever heard of cavitation?

Can you show us where any fuel pump manufacturer says to use a filter with "the smaller the number the better......and before the pump" filter?

They all say strainer or screen element.
