Barry,
Thanks for your inputs.

oil or
fuel and no gaskets or o-rings for carbs, rights? But if these parts

acceptable. The failure is >more than likely due to how the fittings

Here we have two kinds of MoGas: =9295 with Ethanol (max 10%) and =9298
with
very few %. I think that Rotax has approved fuel with Ethanol (like
=9295)
quite recently but never released a CN to define a life-time for the
hoses
and refers that point to the plane (or kit) manufacturer. Or did I miss
something?

Max,
Teflon hose for fuel system components is available from Aeroquip. Their
Aeroquip 666 is teflon. You could replace all your rubber fuel hose with
Aeroquip 666 hose and never have to worry about replacement again. I bui
lt my Europa from scratch with 666 hose. It isn't cheap nor is it light a
nd you should have it custom made for you by the vendor as it isn't a hose
that's suited to home fabrication. But it is teflon and it is impervious
to just about anything and certainly anything in fuel. It also has a con
ductive lining to eliminate static generation which can erode the best hos
e from the inside. It is also covered with a stainless steel braid for st
rength, abraision resistance and safety. You can have it fabricated with
firesleeve or add that yourself prior to installation. It is available fr
om a number of sources in the US. I don't know about France. I purchased
mine from Aircraft Spruce. You can check their website for pricing and i
nformation.
If you presently use barbed fittings for your hose connections you would h
ave to replace them with AN Flared Tube connectors. Steel or stainless st
eel in front of the firewall but aluminum is acceptable behind the firewal
l.
I hope this helps.
