Good to hear the move went well.
I know how it is when it comes to taking pictures, way too many distractions . . . . .

Good luck with the rest. . .

Hi Tom,

Serial - PD4501-278

And while we're here, approxmiately what kind of air pressure should i be seeing on the gauge when running? I don't have any of my books here and i think i remember seeing the gauge right aroung 95 lbs when airing up the bus for transport. I was using a sears portable compressor and it would shutoff itself at around 140lbs. Wondering if something goofy is going on with the gauge in the bus or what.

I'd think that your compressor has enough pressure and volume, but maybe you are not airing up the correct tank? Be sure you are airing up close to where the bus compressor discharges, ie wet tank, etc....just a thought.

Hi Mike

Thanks for the serial number. I think mine stays pretty well at 120 when totally aired up. There should be a 3/4" pipe plug in a line, or near a "small football" shaped cast air tank towards the top of the bulkhead behind the engine. This is a good place to plumb a 90 elbow and run it out next to the radiator with a quick connect. Or there should be a fitting in the drivers tool compartment. (1st outside door on left side of coach, below drivers feet). Where are you connecting your air?

None of my air lines are original, or even in their original places. When i lowered the seat platforms, everything got relocated. I made a homemade sketch of how the lines were plummed, and then ran the lines in the same manner to where i relocated the tanks. I did add an air dryer to the system and placed it inline between the compressor and the first storage tank. I added a quick connect fitting right before that air dryer. What is sorta strange, is that the air gauge will show the pressure drop to about 20lbs in less than an hour, but all the air bags will hold a full charge for slightly over 24 hrs before they start leaking down. Confused?

My guess is the gauge is reading the supply tank, the air bag suspension is fed from the accessory tank and there are check valves holding the air into the suspension.  On my bus the suspension holds for weeks on end, but the bus gauge reads 35 psi after 24 to 48 hours.  Why my bus stops leaking at 35 psi is a clue - to what I have no idea.
