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
On my Cozy, I installed one 3/8" return line to each tank. The
cozy has
one
2qt sump blister under each tank. I will be running one supply
line from
each sump to shut off valve, than small gascolator for the
water and
heavy
contaminants, electric fuel pump and after that in to Y to the
engine.
All
the return fuel goes in to my left (Main) tank. Fuel level
control will
be
done by:
Start and taxi on the left main tank
Take off both pumps (both tanks) running
Cruise switch tanks when left goes down. The return fuel fills
it
slowly, so
I go back to left tank...
At least that's my plan.

Hi, Bulent....thanks for the posting....I discussed this with
the designer
of my SQ2000 and he advised against it, stating that in the event I
failed
to closely monitor my fuel levels, (forget to switch tanks), that
the
continuous overflow of unused fuel from the right tank into the
left tank
would cause a problem once the left tank becomes full. It would
then start
pumping fuel out of the vent line of the overfilled left tank.He
said that
if I go with that system, I should have a pump which will allow
fuel
transfer between tanks.
Dave Atkins suggested that there is a fuel selector that
will send the
return fuel back to the tank that is selected. Makes more sense.
Then, of course if I go with the sump tank, fuel will only
be pumped
into the sump tank regardless of which tank I am using, or even
when running
on both tanks. Hope this helps. Keep building.....we need more
rotary
powered pushers in the air. Paul Conner
How about a line from the left to right tank, located just below
the vent line ? Over flow would go from left tank to right tank instead
of out the vent, Virg
