Ira I also used the R9 Gates fuel injection hose in March this year to repl
ace all of the old- fuel line hose.

I had the same results, the fuel smell went away.

I do not believe the odor of mogas that has always been presenct in my Euro
pa emanates from any of the connections of the hose to connector hardware.
Rather some volatile components of the fuel seem to permeate through the ho
se itself.- When I replaced the factory supplied Gates R7 spec hoses this
year with Gates R9 hose, the smell of fuel was quite a bit reduced. R9 hos
e is fuel injection rated hose with a specified lower permeance to fuel (al
so, longer working life). I used bare hose aft of the tank selector switch,
and stainless braided forward of the switch and throughout the engine comp
artment.

Yes, the better grade of hose helped,
Now I guess I just have to wait for my fingers to heal from mashing on all that
stainless braid ;-)

Remi,
If or when we get another hot day I will give this a whirl and record
the numbers for all. Maybe at Rough River if it's nice.
Best,

For those interested I have constructed and fitted a full wave loop antenna
as per Dave Morris's
designs located here.
http://www.davemorris.com/dave/MorrisDFLoop.html
I hooked up my hand held scanner to the loop comm antenna today, and the
initial results
are excellent. I appear to be getting better reception on the ground in my
closed workshop
than i have had in most of the aircraft i have flown, while airborne. the
ATIS
info from the airport 40km away is so strong I cannot cut it out even with
FULL
squelch, likewise aircraft transmissions from areas 25km the other side of
the airport
(based on airspace freq, Parachute drop at a field I know well) are nice and
clear.
The antenna still has to SWR'ed in yet, and is approximately 2 inches too
long.
oh the aircraft is presently facing more or less east, and the airport is
due south
of me, so the ATIS and the aircraft mentioned is virtually all side lobe
reception.
The loop fits neatly round the fuselage about 100mm behind the baggage bay
bulkhead
total cost for this was about $5 if you are counting your pennies that hard.
