Aux Air: was Dump Valve Rebuild?

[Pete Masterson]

I have s modest sized shop air compressor ... and I've thought about
mounting it onboard to allow pressurizing the system for the dump
valves. But it seems a waste to have to add a 100 lbs of compressor
for such a relatively small task (that is only done every 2 or 3 days
anyway). (It's not just the weight -- but also the space it requires.)

I don't know how long it takes an 8v92 to air up ... but it's less
than 5 minutes for the Series 60 to reach the 'blow off' at 120 PSI.
(Only 2 or 3 minutes to clear the low air alarm at 65 lbs.)

But, this leaves me with a question. I _thought_ I was shown a "shop
air" input in the engine compartment -- but I can't seem to find it
now. I have a air source located next to the AquaHot on the street side.

Is the 'source' connector also the 'input' connector for shop air?
