You should check out the Jet Model Products accumulator on their web site. Their unit has a filter in it after the membrane bag as to insure that no fibers enter the fuel system from the membrane.
You would have to see their demo unit to see how effective this is as to eliminate any air from the system. It will still flow fuel with no air bubbles till their is less than 1/2" of fuel in the bottom!
The unit is made of aluminum to insure integrity even in the event of a mishap.

Hope this helps
