Lycoming O-540, 250 hp, showed a high of about 18 US gph on climbout, so
the standard lines should be more than adequate ....

fuel line! If you are running a Lycoming, acceptable minimum size should beHello Frank,
Got your mail off the archives with reference to your gascolator to carb
3/8"(you will find 1/2" on a Cessna). A 912 Rotax would work find with the
1/4" one you have! The next thing you should buy is a builders manual from
the RAAC Headquarters (1-800-387-1028) or find someone that will lend you
one! (Sorry but I lend nothing anymore, as it appears I may have been taken
for an engine mount I lent someone to use to make a jig! I hope not, but 3+
years is a long time!) This reference manual will tell you everything you
need to do to pass your final inspection, placards etc. Note that you also
need "firesleeve" over your fuel line and some inspectors want it over your
oil cooler lines also! The main thing with the fuel line is that you
ACTUALLY do a fuel flow test, with minimum fuel in the tanks and the
aircraft in a nose high attitude! You remove the line at the carb and must
keep it at the same height as the inlet. Also, the inlet screen (from the
carb inlet) should be on the end of the fuel line. You must get a minimum of
150% of the full power consumption requirement for the engine, flowing out
of your fuel line (on a gravity feed system). Anyone on the list do a fuel
flow on their SR2500 with 3/8 factory lines, finger strainers, etc???(same
size as supplied for rebel) Will it supply your 360HP M14P???? My 340HP
Supercharged Lycomings on the UTVA's burn 52 U.S. Gallons per hour at full
power!!!(per lyco's engine manual) This would require a full flow test
result of 78 G.P.H. if gravity feed, but with a pump you only need (I
believe)125%(or 115%) of consumption, so would need 65 G.P.H. On the last
Rebel with both tanks turned on I got 42 U.S G.P.H. I guess with a pump you
could suck some more out of the tanks. Someone let me know your experience
with the SR fuel flow before my Buddy's is to far along!! We may want to
change the fuel outlets on the wing tanks to take a larger finger screen.
the list was lost into cyberspace. Go to the website and resubscribe!Don't forget the Rebel Builders meeting at Brampton Sunday March 12th - 1PM!
Frank you may be one of the few that didn't get restored to the list, when
