That water separator looks full if it is dump it.

Yes!  It was obviously replaced.  Originally they came with an auto-drain which that does not have.  Look at the floor underneath it, should be a small hole for a water drain hose to expel it under the coach.  The one on 1482 is an SMC part# AFM20-N02C-CZ.  The solenoid valve is VX3114-01N-6G1-B 

I recommend you go to a truck supply and get a bunch of 1/4" DOT tubing, perhaps 20'.  It's bulletproof and lasts forever.  My preference is to use straight fittings with a street ell instead of an elbow fitting.  It's much easier to remove when you have your next problem.  You will eventually need 1/8", 3/8" and 1/2" tubing for other systems, the Bode door uses 8mm (5/16") tubing.  While I generally use DOT fittings I believe a general purpose brass fitting does a good job when a brass insert is used in the tubing. 

The muffler is what I made to silence the air compressor unloader valve when it shuts off.  The Bode door also has one.
