Gas check valve and anti roll over valve ?

I finally got the body Free on our 1977 CJ5, at least I thought it was free until I noticed two fuel lines running up into the drivers rear quarter panel. According to Chiltons these are the gas check valve and roll over valve. My question is how robust are these valves and is it a good idea to change them? They look pretty corroded from the outside. Are these a dealer item or something I can get at a local auto parts place? Thanks for the help.

I have never replaced them and as long as you can blow through the tube and get no resistance or appear to be operational, the vapors are going through it and I would go with they are good. I have a couple of CJ7's in my back field and can check them if you need them.
