The color-coded hoses on the right and left of the tank go to the emissions system as shown. There is one gas line (purple) and one vacuum line (orange) from the petcock to the carbs. | The color-coded hoses on the right and left of the tank go to the emissions system as shown.

==For California tanks without emissions-control systems== | |||
Some people remove the evaporative emissions systems from their bikes, or install a replacement California tank on a 49 state bike. If you have a 3 line tank (California) but don't have the emissions devices, this is what you need to do: | Some people remove the evaporative emissions systems from their bikes, or install a replacement California tank on a 49 state bike.
