Hi, fellow rotary enthusiasts.  I am building an SQ2000 canard pusher

with a 13B. I have two

strake fuel tanks that would be considered "mid-wing". I plan on having

a fuel line from each tank

into my approximately 2 gallon sump tank, and from there it will go to

the fuel pumps, fuel rail,

and to the regulator.  My question is, is it best to have the unused

return fuel from the fuel

pressure regulator go back into the sump tank, or run a seperate line

back up into one of the fuel

strake tanks?
    I am getting ready to put the top on the second strake tank, and it

would be best to install

any and all fuel lines before the top goes on permanently.
     Thanks so much for your suggestions. Hope to see as many rotaries

as possible at Sun-N-Fun

soon.   Paul Conner

Hello Paul,

    In the homebuilts I have been involved in we have always ended up with
the return going back to the header tank and they have all worked well. Some
of the considerations were the length of fuel lines and the number of
fittings, the balance of fuel and tank selection issues ( keep in mind fuel
management is a big killer, kiss ) and the the use of fuel totalisers. I
think the most important thing is to make the system as effective as
possible and simple as possible. I'd say close that strake tank in and go
with the header tank return.

PS You need to test that the engine will run with low fuel levels and very
high attitudes but I would also suggest that if you don't use a header tank
testing to make sure you dont run into problems if you run off "BOTH" with
one tank empty.
