Racor strongly recommends that filters be operated under vacuum rather
than pressure. I believe the idea being safety. Better for a leak to
pull in air than spray fuel.

I am assembling my posihing system. Not clear whether it is better
to put the pump on the pressure side or the vacuum side. Having no
filter on the intake of the pump seems risky. I am using a 2 stage
approach. maybe putting the filter between the filters is an option.
