fuselage back there instead of on the firewall and therefore I only have
one drain in the middle of the fuselage. I added brackets to hold the
"T" and the hole in the skin is just large enough to put a wrench on the
drain fitting and remove the drain fitting if I have to. If I ever need
more access I will cut in from inside the fuselage. That is not near as
likely to ever happen as it will be for the guys that bury rubber hoses
under the floor...
Those drains are a good idea. Now that alcohol is mandated in Ontario
mogas I am having nothing but trouble with my small carbuerated engines.
A water alcohol mixture keeps settling out in the float bowls. It may
not freeze but it makes the engines difficult or impossible to start.
COPA says that Shell V premium is alcohol free for the time being for
STC holders but the MSDS says up to 10% alcohol so caution may still be
order even with that. I'd suggest draining a lot of fuel from any
sediment bowls or carbs if someone is having trouble - unless you see a
separation line, it is easy to mistake separated alchohol/water for pure
gasoline. The mogas that is giving me trouble is all regular grade fuel
from high volume, major oil company, name brand stations and it tests at
5% alcohol as delivered. Water in fuel used to be a non issue as it just
settled at the bottom of my jerry cans and even froze there in cold
temps. Water filters or sediment bowls used to take out the rest. My
soob can handle inadvertant gasohol but the thought of puddles of
separated water/alcohol mix in aircraft fuel tanks is scary. I guess I'm
being forced into putting leaded avgas in it with all the environmental
and engine maintanance issues that go along with that.

After familiarizing myself with my Rebel, and the builders manual, I realized
that the origenal builder had not installed quick drains at a low area in the
fuselage. I have opened up the lower exterior side skins to expose the fuel
lines and started to reroute them to a low area just aft of the rear LG pick-
up point. Obviously I will have to install a "T" fitting in this area. However
there no provisions to access this fitting after the skins are reattached.
How have others addressed this problem?
