At KC I mentioned this awesome bender that is adjustable for all popular metric and standard sizes. I have used it many times for stainless steel and it works flawlessly. I get my tubing in 20 foot rolls, then use the straightener to cut out dipstick tubes, PCV hard lines, brake lines, fuel lines, etc.
