Fine, but what kind of filters are you using and where are they in the system?  Gascolator is NOT a suitable substitute for a filter.
I have a "flat bottomed" sump on my Velocity, and water DOES accumulate in it.  My fuel line to the pumps is cheated up off the bottom of the tank half an inch and there's a test drain in the bottom of the sump to check for water.  One of these days I'm going to make a little "blister" in the bottom of the sump where water will accumulate so I can get it ALL out without removing the sump and shaking it for twenty minutes.
It all counts, and some of it counts /against /us ... Jim S.
