Bernhard,
Are you referring to the fuel cap leaking in the main fuel tank located below the
seats? If so, then remove the cap and notice that there is a screw or nut
(can't remember which) in the center on the inside. Adjusting this will make
the seal against the tank inlet either tighter or looser. It requires a little
finesse to get it just right. Too tight and the locking lever won't close or
is too hard to open. Too loose and the seal leaks. I struggled with this problem
for over a year before finally figuring this out. Now, no leaks.
If you are referring to wing tanks, I don't know what to tell you. Our Allegro
does not have them nor do we need them. I have a 2 1/2 hour bladder which pretty
much requires me to stop for personal relief with one hour of fuel remaining
in the main tank.
The fuel gauge is wildly inaccurate and begins to swing around in flight after
burning off the first 4-5 gallons. I never trust any fuel gauge in any airplane
unless I've calibrated it. Actually, I don't calibrate/fix the inaccuracies.
Instead, I empty the tank and add back two gallons at a time and note the position
of the needle on the gauge at every two gallon interval and note those readings
in our flight manual which is a home-made, small format affair in a small
three-ring binder we keep at hand. Then, I use this only as a gross indication
of fuel remaining. For better accuracy I depend upon elapsed time and known
fuel consumption rate for more precise fuel remaining calculations.
Back in the late 60s I flew a Mooney on a night flight from Atlanta to Miami non-stop
w/ three passengers and landed with less than 20 minutes remaining of fuel,
based on fuel added, due to an unexpected diversion I had to make in-flight.
That is by far the closest I've ever come to running out of fuel in flight.
It scared me enough that I stop for fuel no later than one hour remaining, no
matter what.

Hi guys, as far as the fuel tank leak, loosen the seat belts all the
way to get the seat out of the way. Carefully feel and smell the carpet
on top of the tank for gas. What happens is the rivits under the seat
tend to wear on the top of the fiberglass tank . We cut the carpet with
a 5" slit to expose the wet area and mixed up an expoxy solution and
covered the worn area. Before positioning the seat back we padded around
the rivits with a 2" piece of carpet with a dime size hole in the middle
glued around the rivits. Problem fixed. Thom Riddle had talked about
this also on the list. Good luck. Also in
regards to the question on rudder with the "07 model", I think they did
something with the linkage of the rudder which was an improvement. I
didnt experiment much with adverse yaw but I didnt seem to sense any
problem. Still a plane you cant fly with your feet on the floor.
Fly safe Bob Griffin
