York OBA questions

[KLF]

I assume this is the best section to post this thread, please let me know if there's a better one.

I'm in the beginning stages of installing a York OBA system in my truck, using a York 210 on my 22RE. The compressor is mounted and tested, seems to blow a lot of air, my next task is to get a good solid temporary connection to a spare tank I have, see how well it does at building up air. I did a lot of searching out on the web, now looking for advice from the MUD membership from those that have done this project. Yes, I did search MUD, didn't find much.

1. I'm concerned about the heat buildup on the discharge. I have about 18" of the original AC hose, looks like it has about 3/8" ID. Will it take the heat? Or do I need some sort of rigid pipe for the first foot or so? What about the SS braided hoses that Viair sells?

2. What did you do about a coalescing filter? I know about the Coilhose 8923M that Kilby sells, seems kinda steep, wondering if there is something more economical, although I won't go with anything with a plastic bowl, they blow up eventually.

3. Wondering about the idea of plumbing from the compressor to a check valve, then manifold, then straight to the tank. Use the tank to condense water and oil, then put the filter AFTER the tank, and drain the tank after every use. I have a decent filter on my shop compressor, and I still get a lot of water in the bottom of the tank.

Still not sure where I'm going to put the tank, not a lot of room left.

Thanks!

I know its an added cost, but you would probably mount the the tank in the frame rails, possibly consider aluminum because of the exposure to sand,salt, water.

KLF you are right to be concerned about the heat issue and its affects on the output hose. Rubber hoses fail in short order and even braided hoses don't seem to hold up. I have had success with a 1/4" steel tube that snakes around for about 30" before entering the distribution manifold. This seems to provide enough length to allow the compressed air to cool down a bit. I got this part at the junk yard and if my memory serves, it was a power steering cooler on a mini truck. It is connected to the manifold with a 2" length of rubber tranny hose to help with the vibration.
The setup consists of: York pump, cooling tube, check valve, HF coalescing filter (yes one did blow up), manifold (safety high pressure relief valve, pressure switch), rubber hose that runs to air tank.

Look at the smaller air filters off of a commercial truck with air brakes. They have a heater to dry out the silicate and a filter built in. Some are huge but their are lots of small models too. Pretty cheap at truck salvage yards because they rarely go bad. I use a bendix airbrake pump for my Oba and used a short section of 1/2 hydraulic hose for the discharge this seems to be holding up so far. Another thing to look at for plumbing is the nylon air brake lines and the push to lock dot fittings. The air bag and heavy truck guys have been using these for years and they make plumbing super easy.
