Nilfisk P150 leaking problems!

I have owned a Nilfisk P150 pressure washer for just over two years it started leaking at the joint between the trigger and lance extension.
But when it leaks it comes out of all three joints.
I read from other posts here that it's is probably a new O Ring.
So I decided to buy a complete set, although Nilfisk recommended that I buy a new trigger and then a new lance extender if that didn't solve it (one born every minute)
So I fitted new set of o rings but it leaked the same, however it only leaks when it operates under pressure once the nozzle or Snowfoam is on.
Got another set of o rings thinking it could be the o rings (live in hope) but still leaked!
So I ordered another trigger and lance and it still leaks!
Any suggestions apart from dumping the machine and starting again all because of the business end of the hose?
I tried Pte tape more silicon grease on each o ring!
Very frustrating.

Not sure if you have resolved your issue or not but both my son's P150's had the same issue and it is actually the intermediate tube that split right along the reinforcing plastic vein. You cant see the split until you put pressure on it like you have experienced.

The past you need is Nilfisk Intermediate Tube G5 Lance 127440051, North West Pressure washer part# 12744005.
