i need to replace my VCV vent control valve. The valve that vents the intank pressure so as not to have fuel come back up the fuel filler neck. I have tried various parts vendors and so far no luck. Ive even tried matching it to the toyota highlander VCV. But no luck does anyone know where i can purchase just the valve not the complete charcoal canister? Anywhere besides the dealer. Or a quick fix that wont result in a P0455 evap code?
