Once again I want to thank everyone for their advice. Got all air leaks fixed. I ordered a NAPA DQ6020 lower repair kit and a NAPA DQ6026 upper repair kit for the Air Dryer/Purge Valve. The rebuilt job took me about an hour and everything worked at the end. Thanks again.

Just removed the dryer assy; no data plate. There are two numbers stamped into the dryer assembly cast body; one looks to be a part number N4250B so I assume the other number might be a serial number.

When I started my M35A3 last week after sitting all winter, the air pressure didn't come up like it should. It's just below 60PSI. I checked for leaks by listening and the soapy water test with no leaks found. I drove the truck a couple of miles and the air pressure comes up to normal after a...
