Are you talking about an additional valve that's "upstream" from the one that's closest to where you hook up the slinky?
I had one on my Outlaw also...
I kind of decided that it was there to offer some "insurance: if the other one failed.
I used it while I was on the road; but would open it up once I got hooked up at a Park...
