Ken, i have one like that on the Legacy. It does not use the retaining nut though, it just pushes on and clicks. looks just like the 08+ fittings at the tank, the 2 plastic pieces that you push together and slide it off.
I believe I got it from Parker on Baseline in Mesa.
I'm thinking that yours may be a little more secure, however..
