Fred:
My filters were upstream of the fuel seletor which meant they were
basically at the outlet of each tank feed. I thought this was reasonable
and so did everyone else who gave it a cursury look. However when you are
50 ft off of the ground on take off reaching to switch tank sides for a
good filter really doesn't cut the mustard that close to the ground.
Putting them after fuel selector valve and in front of each electric fuel
pump gives you more options. The normal procedure for takeoff and landing
is to have the aux pump on also. So if you do get a clog by chance you
have a parallel path. And since you normally only run the primary pump
for flight the filter in front of the aux pump is also less likely to have
some garbage loading in it.
