Bryan,
Having the stock system myself, I've had no failure of any
kind in 860 hours to indicate a need to run other than fuel from wing, to
header, to engine. Additionally, I have a filter in the line from the
wings to the header. For me this is a convenient filtering
technique.
I may be over simplifying your T commentary but many an
aircraft has left the sky to only find fuel migrating into tanks where we
thought it shouldn't. Take the Voyager for instance. Check valves
may be an additional item needed to make your system run in both ways (to header
or to engine).
>but they would feed at the same
time equally< This is simply a
hope. In reality, your rudder ball centering skills will determine from
where the fuel comes.
For
the 320, the 1/4" lines would probably be sufficient. I draw over 20 gph
occasionally when racing. I like my 3/8" line from the header to the
engine.
Regards,
Larry
I want to run this idea I have past the group.
My current set-up is 1/4" lines coming from my wing tanks to the my header.
Then a 3/8" line feeds my engine. In this configuration I can only
feed the engine from Header only. This is the stock Lancair 320 fuel
system.
I would like to be able to run my engine off my wing tanks if needed but I
don't want to re-plumb the wings with 3/8" lines. Can I connect the 1/4"
wing tank lines into a "T" with a 3/8" exit and run the line to the selector
valve? Essentially the wings would not be able to be selected but they
would feed at the same time equally.
Would this idea work? And if so what type of Andair valve would I
need? One with just a Left/Right/OFF And I would have them custom
engrave the bezel to read Wings/Header/OFF
Thanks
Bryan
