   Hi All, It?s been a while since I?ve been on the newsletter between
   work and trying to make progress on the Long EZ.  Anyway, it?s time
   for the Fuel system and I wanted to get feedback from the group on
   my design.  I attached a PDF of my concept which utilizes 2
   different sumps, 1 rear cockpit thigh support/fuel sump and a 2nd
   sump in the hell Hole.  The reason for the added sumps is to try to
   recover some of the fuel I will be losing due to installing Infinity
   retractable gear.   Anyway, my assumption was a P-Ported 13B with a
   TO4 turbo so the lines need to be able to keep that thirsty puppy
   humming at WOT.  I guess it would make about 350hp at WOT. Anyway,
   can you guys take a look and shoot holes and make recommendations.
    I look at the fuel system and Engine installation design as the
   most critical systems we develop so I want it to be right.


   Thanks

   Mike C.


I'd put a fuel drain in the lowest part of each sump where lowest is
when the ship is parked.

I'd put the pumps in the last sump.

I don't see provision for fuel return.
