Having swapped out the jet for one I had in my spare box I had no leak so I put the original jet back and no leak. I moved the jet up and down and suddenly it leaked again then noticed the jet bearing moved a bit. Tightened the large nut a further flat and no leak. I thought I had it tight before.
I will check the tightness again in the morning.
