Quote: This is the second line as directly under the firewall by the frame rail there is a flexible hose connection. This line also has the check valve in it where the flexible hose connects going to the breather cap.
I have seen this also on a 1972 Satellite parts car. My challenger has a build date of 6-71.
I have a picture of an original car and I don't see where it is a two piece line. It is one piece from the frame rail to up by the shock tower.
