Sump Drains

[Ron Landon]

I'm about to flip my LongEZ build to mount sumps and glass the strake bottoms.  I've got 2 extra SAF-AIR flush type fuel drain valves.  Since I have them, would adding the fuel drain valves to my sumps be an addition worth having or an unjustifiable waste of build time.

I have never encountered a need to drain my sumps.   Maybe a fitting with a cap would be a better alternative but really, it's not needed IMO.  I almost never find any water in the fuel but it could be drained by the leading edge drain or caught by the gascolator. 

OT: Do you plan to install the two vent lines per tank?  Those are not in the plans but history has shown they are needed.

Hi Kent, 

Thanks for the reply and for confirming what I suspected.  I guess if there was a defensible reason for drains in the sumps there would have been activism promoting it long ago.  And yes, I have 2 vent lines per tank, one each from forward and aft tank limits and plan to run them through a common manifold above and behind the passenger seat Berkut style before exiting below.
