Hi all….

So I had a rough idle on my l322 about 18 months ago, turned out the boost hose from the top of the supercharger going to the fuel pressure sensors had fallen off.

Any I pushed it on it fell off…

I bought a new one with an new elbow on it and it was mega tight and snug and car ran lovely - then yesterday got a little bit of a rough idle popped the bonnet and it’s half Hanging off again and the hole in the elbow seems to enlarged itself…

Any ideas? Current stable:
