I was able to remove an olive from the blue tube with care,
I will give it another try after dinner, but mine look to have a t shape insert with an olive “like” around…
Guess i could try to burn the tube to get it out… as any sort of cutters or prying tools will definitely score, scratch or ruin the fitting

Are there any extra fittings in your existing compressor or valve block, that are not standard.
The T piece in the end is so the olive doesn’t collapse the pipe when tightened, it’s a little sleeve that goes in.
But that’s not standard if I remember correctly.
Suggest you stand back and have a cuppa while you look at all the bits you have. While drinking your cuppa take some pics and post them.

@svenology Upload pictures of both the old & new compressors showing the fittings. Then we can see what you have & advise.
Success!!!
New compressor is finally in. Had to wait forever for parts from Amazon... can't seem to find at any car parts store.
I basically used a coupler for now between the hose from the EAS box that was part of the old compressor, to the hose of the new compressor that came without any sort of fittings that I could use to attach.
So now I can technically "quick disconnect" my compressor....
Not sure this will be the final solution... (any comments on if this is a solid enough solution) but my olives for doing a new compression fitting are still in delivery hell... half of italy is on vacation.
But I have all the other good stuff now.
I will also upload some pics after dinner of my old compressor and new compressor and the hoses as I found them....
After the install, new compressor ran... 1-2 minutes into it, vehicle raised... 5 minutes maybe for being at proper height.
Then kept on running a little longer.... stopped the first time.
Vehicle raised in less than 2 seconds to max/wading height. I have it locked there now for about 45 minutes.... no drop. No sounds.
I did find that even when just sitting there with the engine running the compressor cycles quite a bit.
So will be interesting to see how things develop. Maybe there is some sort of leak.
Does anyone know how much these compressors are supposed to run?
Like out of a minute of time for example? 20%, 50%, even more? Obviously depends on how much work the suspension is doing. But presumably the pressure switch for the tank controls the running and wants to keep pressure at a solid 150PSI I'd assume!?
Thanks again to all of you who have contributed with great advice and good ideas!!
Rover on!

You could have the height sensor out of whack. Does it move up and at the front or rear. Like it's dancing?
See below what I was dealing with.
#1 new compressor came with new air line, but the compressor side was completely different from the original Dunlop compressor. (my new one is from AEROSUS... looks identical to the dunlop... but also all dunlop OEM do sell exactly like that one... with a cut off end on the EAS box side....)
#2 it might be that my old air line was not original. either way, the connectors were not removable, so with my new compressor I was stuck at a dead end, as neither did I have any sort of ferules or olives to make a connection, nor could I reuse the old.
I ended up using a quick connect adapter to join the old and the new line for now. Seems to be working find and will be really easy to connect a new compressor to for all future.

Nothing is dancing or was dancing... it acts exactly the way it did before the compressor failure.
In my eyes, EAS behaves perfectly. No dancing, no sagging, no weird states after power off.
Also, achieves any ride height immediately within seconds.
I had EAS issues before once on another P38a in the US.... so I have seen all the weird behaviors...
When I got this one 6 months ago, EAS was perfect and it has been flawless until 2 weeks ago when the compressor failed.
Now the compressor in there was rebuilt... it says that on some painters tape...
But was it because a failure of another EAS component???
... at the moment the only possible failure I can even imagine would a leak/problem in the air feeding to the storage tank.
Assuming the circuit is compressor -> tank -> EAS ports -> air bags
As the vehicle holds height for weeks, rises to any height immediately, no errors or issues.
Hoping it was just a bum compressor.... the truck has 200k miles... visual inspection of airbags so far shows no cracks.... the fact that the car doesn't sag on any corner would indicate to me that there are no leaks in airlines or bags....
Just felt the compressor was running quite a bit once installed... but then again I have no idea how much it should run....
and the whole system was empty.... so lots of air to refill....
Understood, I think my original pump was around 8 minutes to fill the tank from empty with a door open for no interruption ? (correct me if I'm wrong) 
..
Hopefully you've suffered just a tired pump
.. Hopefully you've suffered just a tired pump
If the doors & tailgate are all closed, and the car is low, then the compressor is feeding the tank and any airbags that need to rise.
To fill the tank only a door or tailgate needs to be open.
Your compressor failure two weeks ago could either be gradual aging & it eventually gave up, or it was feeding a leak, that either occured recently or has been there a while.
Now you have it working, definitely check the entire system for leaks, or you will be replacing the pump again !

Thanks for the intel on the tank still being filled with a door open.... didn't know that. Makes sense though...
I will keep observing.First test drive yesterday went fine.
This morning, after parked on level surface last night, the truck still is at same height and leveled on all wheels as it was last night.
