i was attempting to bend some of the new fuel lines for my 2A last night....5/16" line, aluminum. I have one of those cheapy benders with no moving parts.....looks like a small scale conduit bender. the tubes kept flattening out. it didnt support the sides of the tube well enough for the 5/16" tube.....would probably work better on larger tube though. I tried packing them with sand, which is an old trick some aircraft guys taught me, but that didnt work.... is there a hand held bender that works better? i did a search online and found something like this: KD Tools Tubing Bender - Model KDS2189 at Sears.com this: Imperial Triple-Head Tube Bender with Roto-Lok Indexing Handle - Model 47299 at Sears.com and also this: Tubing Bender - LIS44000 are those any better? it wont be the last time i have to bend tube for brakes or fuel so i dont mind buying a good part this time. the cheapy bender i've had since high school.
