Picked up my Aero tank today. Very happy with it, except I didn't order it with the two tiny hose fittings to attach to the original emissions control lines that connect to the charcoal canisters. How much do these matter? I can deal with a little gas smell in the garage, but my garage is right under my living room and adding them would be easy.

You only need one to run to a charcoal canister and it would also serve as a vent for the tank.
