I need help with my air compressor setup.
1. What fitting do I need that goes in the tank outlet - the opening is about one inch. Campbell Hausfeld said I needed a 3/4" ball check valve, but I checked and 3/4" isn't big enough.
2. I'm planning on operating a nitrous pump, and it says it needs to be oil free. Can I just put a couple filters inline to dry out the air? I bought a regulator/filter/lubricator, can I just run that witout the lubrication aswell as the other inline filters?
I'd appreciate any help you guys could give me on this. I'm really needing this compressor up and running right now.

I'd get ready to buy some pipe if I were you.

I would set up 2 drops if you really want to run the lubricator. You will also want 2 hoses as well. Set up one drop / line to run without lubrication, and set up the other to run with. Me, I just oil my tools occasionally, so I don't run a lubricator (you do not want lubricating oil if you ever plan on painting, sandblasting, etc).
I've got 2 drops in this picture:

One for tools (on the far right side, using 1/4" fittings), one for paint (in the middle of the pic, after the additional filters, with a 3/8" and a 1/4" fitting). I use 3/8" fittings on my HVLP gun.
Anyhow, I'd suggest wall mounting your filters etc, and using galvanized, black pipe, or copper to make an air system. I had a custom rubber hose made to go from my compressor to the wall:

The fittings on my hose are 3/4" NPT.
My whole thread is here, if you're interested.

One thing to keep in mind, that filters / watertraps placed right off of the compressor aren't as good as one placed 'downstream' a bit. If you give the air some pipe to cool down in, your traps will do a better job of collecting the moisture. Also, think about some way you can rig up a valve to drain the tank. My tank came with a tiny valve stuck to the bottom, I would never have been able to drain it. I replaced it with an elbow, an extension, and a 1/4" ball valve. Easy to drain now.
