Weird solenoid looking thing

[BryanS]

Some vapor canisters are much simpler than the one in the picture. My ‘75 has one hose to the gas tank vent and one hose that used to go to a dedicated vapor port on the Quadrajet. The carburetor port apparently only vented under certain throttle conditions.

I now have mine vented to atmosphere (added a brass fitting on the air cleaner body) because I have a newer Quadrajet. For a while I also tried using a T in the PCV line, but it seemed to lean out the idle a little too much.

This is an 83 when they really started to get crazy with hoses and lines.

I was thinking about something really simple like you describe…vent line to a carbon tank and that’s it..or just some kind of filter on the vent to keep stuff out. Frankly I like the smell of gasoline
