It happens mate, mine came off at full throttle at donington a couple of years ago the metal clip on the fuel rail inlet came off on mine, such a poor design on the kv6 offers still there got an engine loom if you need it 👌🏼
Sorry to hear this mate, at least you're honest. Most people wouldn't admit it. I admire your patience whilst the cows are trolling you in the background for your mistake 🤣
