1970 CA emissions gas tank question - 08/22/13 07:51 PM
I am going to change the gas tank on my '70 Dodge Dart that was originally equipped with the CA emissions package. That means the tank has the 4 hoses on the left side that go...? My car is exempt from smog inspections here. Do I need the 4 hoses or can I just use the standard tank that doesn't have them?

Yes you should have the 4 tubes, they go up to the vent tube in your trunk next to the filler tube. Yes you can use a tank without them but your vapor return line will also need to be eliminated. They are available as a reproduction with the tubes if you want to use them

I was just reading up on the vapor emissions control system on the internet and it appears that at some point there was a line from the tank to a charcoal canister, and/or the PCV valve. All that stuff is long gone. So, anyone know what my options would be now?

you can cheat a wee bit- use the old return line for the efi return- but at the tank- use one of the lines for the efi return- cap off the rest. use a gas cap that has a vent or you will cause the tank to collaspe due to the canning effect.
