Necessary to run fuel filter after pump in Aux pump setup? I looked at a few vendor fuel systems where they have the aux pump come on with with a hobbs switch.
I see they put pre-fuel pump filters like 100 microns etc... Or a fuel sock before the pump, but nothing after the pump to the rails.
I figure the reason it may not be necessary to put a 10-40 micron filter between the pump and rails is because the system is only used under boost and for a few seconds.
Hoping to get some input as to why most vendors do it this way.
