As long as you put both pressure regulator and oil filter ( before the pressure one ) you should be fine doing that.
Essentially then you'll need airbrush, hose, both the above regulators and some paint. Easy
I don't buy much from ebay, not had a lot of good experiences with it so don't use it, everything airbrush aren't far from me so I usually drive over and see them, hence the constant recommendations to them from me. They're good people, know what they're talking about too
