After Many Years Problem Child Cummins Air Brake Compressor Defect Finally Solved.

I'm installing an air dryer on the truck that has a notoriously unreliable air brake system. This air brake compressor is made by Cummings, and it has been the bastard problem child, as far as air brake compressors go, for many many years. I have repaired and rebuilt many of these air brake compressor heads, and I am only now just finding out that a huge percentage of these manufactured trucks never came with an air brake dryers. I can't believe after all these years, I'm just finding this out now. But this is a huge eureka moment for me given all the headaches all the truck owners have had over the years.
