Isx but Volvo part for air line fitting from compressor to governor.

Volvo part number 8397965. It is the brass fitting that has the green air line going to it.
Cummins does not have this part and as it is a quick connect it can leak and cause the top air gauge to fall surprising fast, 25 psi in a minute. I have been chasing air leaks for the past two weeks. Could not hear the leak. We sprayed everywhere with soapy water and no luck. Finally just started to change stuff. Two air bags on rear suspension. No leaks but cracked. That helped. The quick connect on the supplied air to the bags, the fitting on the cab bags, the air tank fittings , the air tank drain fittings and finally the fitting below.
Next to be done is the left front air bag 20462941 199.00 cdn and the final rear air bag of the four 8829 firestone. volvo price 104 cdn.
Hope this helps someone.
