As I have already said if the tank is full there is more than enough air to raise the car to standard height. No air is going in the tank.
P38A car on bumpstops, will not raise

I go with the leak from pump to tank.
Is the exhaust leaking?
Why is the inhibit switch pressed?

If it was leak from pump to tank, would the compressor stop after 7-8 min?
Be worth leaving doors open for 5 minutes after compressor stops to see if it fires up again.
That will steer us in the right direction.

It will if overheats?
Yes but he said it didn't get hot.
If he leaves the door open when it stops and the pump doesn't start up again, that confirms the tank is full and the air is leaking bag side.
If the pump starts again, it's leaking tank side.

Not sure how hot too hot is
Makes sense to see if pump starts again
Do airbags always raise as a pair? ie if one rear bag doesnt rise does it stop the other one too?
Or if no bag rises then must be a main line and not connected to individual bag

All bags front and rear are separately fed rears rise first then fronts. Fronts drop first then rears all about headlamp aim.

So if none go up then it could be a mainline leaking either too or from the tank?
Yes, but the valves to both rears open at the same time so if one bag or line is open ended then neither will go up.
The gallery in the valve block will be common to all the valves.

True but the high volume leak would be audible unless the OP has hearing problems. And would also produce both rear valves stuck shut fault.

It may be worthwhile checking the dryer for air leaks and checking the contents.
Undo the airbag feed pipes from the block.
Then try to raise the car, if they all blow air then the problem is further on.
If they don't, then the problem is possibly in the block.. None return valves the right way round?
