At the wing roots, where the 3/8" aluminum fuel lines attach to the rubber line section before entering the fuel tanks, do y'all make a bubble flare on the ends of the aluminum tubes to insert into the rubber tubes to help make a better seal?
An AI recently told me to do this, so I bought a cheap bubble flaring tool and made some flares with it. After a lot of practice, the tubing continues to be scored by the arbor plate (even when armored by tape) and the inside of the tube, immediately below the flare, may be cracked but I can't see it well enough to be sure.
The bubble flare tools I have seen are all metric, as is mine. The 10mm arbor for my 3/8" tube is a bit large but holds the tube tight.
What should I do to make better flares, or should I forget the bubble flares and do something else? I can return the tool if no success.
Thanks
