Hello, I'm trying to figure out my evap issue This is my 95 legacy automatic, with the charcoal canister under the hood When I go to fill up at a gas station the pump always cuts off, and I can see fuel vapors pouring out of the filler if I move it back and fill up that way. I believe this tells me the line between gas tank and charcoal canister is clogged. Diagnostic: I took off the line going to tank from canister, and removed the 2-way valve (Part 14) I blew air into the tank bound line with a tire pump, and could feel air gently coming out of gas tank: so I guess this line is clear I blew air into the charcoal canister and could feel air coming out the other line, so I assume canister is clear Blowing air through the 2-way valve is very difficult, but I can (with my mouth...) I suspect the 2-way valve, but I have no idea what it's supposed to act like. Looking through FSM I did not find any instructions on testing it. Can anyone tell me how this part should behave or how to test it?
