This is the drain daily rear discharge muffler, right? Does it purge on it's own at all? It does have some wet oil slobber evidence.
This is the rear tank drain as well, right?
I'm installing pull cords on my front tanks later and the under driver tank is easy. Expecting lots of junk to come out of the front tanks today and then I can monitor them in the future and see how much is making it past the dryer.
