is the fuel tank Toyota corolla 1985 AE82R vented or not
My model does not have a charcoal canister. South Africa model. There is a large pressure escape when opening the filler cap. The cap is a solid bayonet type.The problem is that on manily very hot days there is a irregular engine hiccup/splutter, which I suspect to be as a cause of the pressure build up in the tank. Why does the filler neck have a bypass port, which seems to go back into the tank. The diagrams I am able to get from the internet are not very revealing.
