The way people handle old fuel lines drives me nuts

I keep seeing guys at the hangar just yank on fuel lines to get them off fittings. They think a quick pull does the job. It matters because you can crack the fitting or leave a tiny piece of hose inside that you won't see. I learned this the hard way about six months ago on a Cessna 172. I rushed it, and we had a small fuel weep after reassembly. Now I always use a proper line wrench to break the seal first and then twist while pulling. It takes an extra ten seconds but saves a huge headache. Has anyone else found a better method for those stubborn, baked-on lines from the 80s?

You're making it sound like a cracked fitting is a sure thing. Most of those old lines are tougher than you give them credit for. A good yank has worked fine for me for years without any leaks.

Your luck isn't a maintenance plan. It's just waiting for the wrong person to give it a yank.
