Sounds like the pump could be on it's way out. That's impressive if the car is on the original Airmatic parts at that mileage.

Yes the car is still running good but the ride is getting rough I found out my front right shock is bad the valve in the inside needs to be replaced and my air valve block is bad to cause the car pumps up but won’t keep the height for to long and I put a new pump in so I don’t think it’s bad

If you still have a leak somewhere it will wear out the pump due to it running way more often to keep up.
You could always go with a coil over setup.

You won't go far on this system without some kind of monitoring. The computer will not show you problems with small leaks until they become big leaks and whole system collapse. At this point you compressor is shot from working overtime.
Right now several $150 scanners will read airmatic. When I had trouble with mine, such option did not exist, so I bought some fitting and add pressure gauge on main line.
That did allow me to make sure my system has no leaks and when it did, I could hook up shop compressor to the Tee and "go under" with soapy water.

The 4 mm tubing is cheap. When I was installing the gauge on my wagon, I had to buy like 100 ft of it, so still have lot left overs if you need it.
But you assume the leak on glued part, when it would be good to confirm it with soapy water.
I fixed my system to the point where it would hold 120 psi overnight and compressor would never come on unless big temperature or load changes.

I installed new Tee on the line, so I cut the tubing and installed compression fitting.
Originally MB is using "shark bite" fitting, that easy disconnect after pressing the outer ring in.
Those are easy to work on, but on reassembly easy to have leaks when teeth mark goes under oring. When I see some damage on tubing end, I just cut it off.

I found it on ebay.
Again, if you need few ft of 4mm tubing, I can send you for cost of shipping. I am out of town right now, but will be home next week.
