Pokeys air leak

[doug_ngl]

OK, As I understand it, The 2 air gauges on the dash only monitor brake
air pressure (not suspension pressure). Under the bus, about in line (F
to R speaking) there are 2 air tanks, one for the front brakes and one
for the rear...I assume. I think there is also a "wet" tank somewhere,
further toward the compressor I would guess. My LH dash gauge bleeds
down many times faster than the RH one (when I shut the rig down). Now
the questions:
Does the LH gauge monitor the air in the LH tank (sounds logical)?
Which tank is for which end brakes? (LH for front? LH for rear?)
Where is the wet tank located?
Thanks as always, still cold here in Gunnison, Doug
