I have fitted 5/16 aluminium pipe for all my pipe runs except the tank
drains which are in 1/4 and use 2 of the same type of fittings as supplied
with the tri-gear brake kit . I have used AN fittings through out because
they are easy to find and if you have to replace in service again easy to
source.
As my inspector pointed out, the Rotax engine does not burn a lot of fuel
and has 2 carbs so there is not much fuel flow and very small jets in the
carbs so greater chance of a fuel blockage. I have fitted the 2 in line
filters Europa supplied as well as a gasolator with drain .
I would have happily lent you my flaring tool [68.00 from LAS] but it was
stolen in November along with all my tool and any copper they could find !
Good luck Richard
