Will try that next wkend see I've I can trace the leak
I have been following this as I have been there and felt the pain, long ago before I had the internet and LZ and it’s experts to help me.
First off I am no expert.
I fitted the valves to inflate my bags, but it is only a band aid to mask the problems. But it got me by till I got my sh** together. I know the pain when it’s your only transport.
All the advice given here has been great and very helpful. For if and more likely when I have to tackle it again.
So now my 2c worth.
How did you fill the tank line? With an airline and then try to force it back into the collet? (not the best thing to try and do)
You would have done better to have all the pipes seated correctly and go in through the compressor discharge line. This way for me that is the other side of the check valve (been a lot of years since I dealt with it ) and any air would stay in the tank or line if no leaks. You would also be checking the “whole” system from the start. (Except the compressor).
Am sure @wammers will correct me as to if you would need to make the compressor run so block opens a valve to fill tank, but that’s not hard.
I would just say follow the steps, of the advice it is right, cutting corners usually ends up in going back to step 1 or spending money on things that aren’t needed.
Good luck.

Problem with your advice is that you are still looking at the whole system for a potential leak, whereas pressurising individual parts quickly shows the line where the problem lies.I have been following this as I have been there and felt the pain, long ago before I had the internet and LZ and it’s experts to help me.

From all that has gone before we know where the problem is Keith. Leave him to it, if he doesn't want to listen to experienced advice. Let him get on with it.

Total waste of time. You have a leak in the storage side. Pipe to tank or tank itself, my bet is pipe. Find it.

Easiest way to check tank lines & pressurise the tank is via the drier pipe on port-5. Get an 8mm schrader valve at connect workshop air line. This allows air to flow past NRV into tank, and will show if the NRV is round the correct way and if the tank pipe is leaking. If it's all working the NRV will hold the tank pressure.

Connecting to drier pipe from port 7 would enable drier, NRV1 and supply line to tank plus tank itself to be checked for leaks. Although i am fairly confident NRV1 will be fine on a new block. .

Me too, especially as I seem to remember it came from Kurt.

Seem to remember Dopey having a leak in his air drier not so long back. Recall Saint going round, finding and fixing, IIRC.

Quite possibly but before you can find a leak you have to have pressure in the system. He has a leak, almost certainly in the feed pipe from the block to the tank that is allowing the entire compressor output to leak to atmosphere. Until he finds and seals that his EAS is dead.

Can't get the 6mm pipe number 6 to stay in the valve block it just pulls out any recommendations appreciated

Is the collet broken or bent? Are the 2 O rings in place? Use the collet from your other valve block if necessary..

Have done the soapy water test to see if it's leaking?
