Thank you very much Jon, you've highlighted something which I had overlooked.
Your diesel doesn't leak because the 'O' ring isn't subjected to the movement which I've identified as the cause on the KV6.

That's exactly the premise underlying my solution Peter.

Thank you Peter.
That's very valuable evidence which demonstrates that it's movement which is responsible.
