dumb question: evap canister hoses

[97ranger11]

My ranger (97 2.3) has always occasionally thrown an evap code I just lived with but after some hvac problems and lean codes from a vacuum leak I'm just overhauling the whole evap and egr system and replacing all the vacuum lines forward of the firewall.

So the canister has 4 ports: 2 are about 1/4in with one hose going to the fuel tank and the other going to the purge solenoid. That leaves two ~1\2" ports on top sticking up with nothing connected. Did some digging on YouTube and the only thing I found was a video that wasnt too clear where there were just two rubber caps on the ports.

Is that right? If not what goes there?

Reroute tank vent line into cabin for on demand gasoline scented air freshener.









....seriously do not do this.

Edit: also does anyone know if the purge valve is directional? I figured not but it's not completely symmetrical and easier to blow (slightly) one direction

Only thing I'm missing is a lighter and cig

My purge valves were directional on my 1985 v-8 351W.

I had never seen a four port canister, that I could remember, and I owned a 1997 Ranger 4.0L, so, for anyone curious:

Amazon.com

Now, on my V-8 (from Colorado) , it had two canisters. If memory serves me correctly, the bigger ports went to a row of 4 valves, which in turn were connected to ... two thermactor pumps!

I would suspect the bigger ports were to feed a larger volume of fumes to a single air pump, in an area that required stricter emissions .
