I found the one I have on the net:
http://www.thetoolwarehouse.net/shop/THE-418.html
I've ordered from this place before and gotten good prices and 3-4 day delivery. The good thing about this one is you don't have to hold it against the fitting - it snaps on leaving both hands free to manage the grease gun.
There's something behind that Chevron? I never really paid attention and pass by there once in a while - assuming you're talking about the one right next to the northbound on ramp. I'm up off of Windward (exit 11) not too far. Coming up from Ellenwood has to be a killer commute! Not that mine is any better... I just don't use the freeways
