An experienced mechanic is here and decided to try this to reduce dripping fuel lines on a motorcycle. The easy answer was a spring clip given it was a factory and tight work space between the V heads. The pliers in his hand squeezed the first to fit the fuel line before reattaching it to the faucet. The pen broke in my hand. This style has never been my favorite or even my favorite hose clamp method, but in over 30 years of mechanics there has never been a click like it's brittle and cheap. I thought it was an accident - especially since it broke on both sides in the middle of the fault. I could see that it has a defect in the metal and is breaking, maybe across the whole piece, maybe on either side of two separate pieces of metal. no way. The second, as usual, squeezed twice - for the third time he clicked at the hinge points of one of the ears. WTF? Now I'm doing ten compressions on a few more and no problem - putting one of them on the bike because I know it's risky but even if it's a temporary fix it will get him home from a friend, where the gas leak started. Everything is assembled and I'm about to start the bike when I hear a click and the metal bounces and falls to the ground. The number of things I had to remove to find the problem so there was room to fix included removing the saddlebags and crossbar, the seats, the gauges, the controls and accessories, the gas tank and all the other vacuum lines and Fuel hoses to get there. one. Now that everything is assembled, the metal breaks before starting. I gritt my teeth and zip-tie him to take him home. No leaks and no security but now I'm starting disassembly again and while it's tricky I'll put a good old hose clamp in there so hopefully I never have that problem again. I knew better than to use that cheap Chinese junk to solve a problem I didn't want to go back to. Even an old mechanic can make a youthful mistake. I bought this kit a few days ago for another mower issue that got me thinking. I went out and wiggled the hose that had the yoke on it and it didn't break, but I noticed that it lost spring tension and I could twist it by hand on the hose. I've never seen that either.
