My only reason for doing it this way is that I want the reservoir. It speeds up the process of airing the tires. This is actually a very common setup in four wheel drives. The only thing I am doing diffently is powering it with a 12v compressor. Most off-roaders use an engine driven compressor. But the space in the engine compartment of an X limits this possibility. It's a matter of personal preference. I have seen it done both with a tank and without. I find that I like the setup with the tank better. And since I have the ability to do it that way, that's what I plan on doing. There's really not a whole lot more to it than that.

Please explain the need for a tank.
The ARB compressor fills tires almost as fast as the QA2, and works both diffs just fine.
