Factory air tank? Anyone have size or info?

If you ordered an air powered accessory in a light duty truck (air seat, air shocks, air horns, whatever) you had to add the vacuum powered compressor and the little reservoir tank.

Together they were part number 2234296. I cannot find a part number for just the tank.

I don't know if it has a check valve or if it's just a open reservoir.

I had hoped to be able to run air shocks and air horns off the same PCV-vacuum-hose compressor (GM Power Pak) but don't want the rear end to lower when I hit the horn!

Now if the PleasureLift regulator doesn't bleed off pressure from the supply side, I think I'd be OK anyway, but I don't know how it works yet.
