Where is your selector valve?  If it is on the floor up front like an EZ 
you might be able to suck some air through the selector or cavitate on 
the long run from strake to near IP to sump.  What if you went with the 
system Tracy uses?  No selector - transfer fuel from transfer tank to 
draw tank as needed and draw / return to draw tank.  Gravity feed from 
draw tank to sump, boosted with Facet.  You have most of the plumbing in 
place and it wouldn't be a big deal to convert.
Do you really REALLY need a selector? ... Jim S.
