Air fittings in Vegas on a sunday

Long story short... were putting a Kelderman kit on a superdudty in Las Vegas in a rental house driveway, and had to mount stuff differently due to an auxillary gas tank in the back. I need to chase down some fittings. I need to connect 2 Viair 3/8 lead lines to a single 3/8 port on the tank, and Im about a foot short in length. Im tired. I dont know where anything is in this town. Thanks for any help. Stop by the Dino Fuel Alternatives booth in the South hall in the upper level and say hil.
