SP36 air leaks

[williamcharrison]

The air leaks are fixed on my bird. It turned out to be cracked hoses
on the front brakes and a leaking quick disconnect hose near the
compressor.
Meanwhile when my mechanic replaced the hoses he found the left front
air tank had about 3qts of water in in and the right one over 1qt.
He put remote release valves on the front tanks but could not find the
rear one (and neither could I). The water indicates to me that the
air dryer needs serviced so I need to know where it is and how to access
both it and the rear air tank(s).
