what I'm saying is that the other lines might be clogged, thus contributing to the problem-- just a brainstorm-- basically, look at the whole thing and don't assume it's the CC just because that is where you see the problem.
The charcoal does get saturated and ineffective by overfilling- that's one reason why all vehicles say don't overfill= No room for vapors. they either go out the gas fill or saturate the CC and emissions system. I think the gas fill is about the same level as the CC? So if you fill it to the neck, it's gotta equalize somewhere at the CC end.... and that is designed for vapor, not for the liquid fuel.
The bottom line actually sucks in fresh air but if you are oversaturated, of course fuel will spill out. That's a lot of fuel since it has to make it's way thru all the charcoal.
I *think* maybe several things or a combination of these:
1. there are two ball bearing check valves at the top of the CC. The exit valve may be stuck shut, giving the fuel vapor no where to go but down
2. the fresh air inlet (at the bottom-where you see fuel leaking) is clogged up w/ dirt, not letting enough air in to properly allow the CC to work
3. the charcoal is completely saturated and ineffective in absorbing the vapor (pretty safe bet this is the case w/ the charcoal at this point)
note that the CC is very simple. the only moving parts are the two check valves at the top.
also note that I am no expert!
so maybe people can explain the system better, i don't know the extent of it.
