Hi all! I have a problem with my suby when i drive hard in corners. If the fuel level is over half ,my fuel starts leaking on my rear right wheel and bumber. It seems that the fuel comes from the fuel filler cap ,but the cap is tight. I want to ask if the V4 Sti have a one way valve in the filler neck?(i believe it have) I don't understand how the fuel goes up to the filler cap (because the interior of the cap is wet with fuel) If i drive hard with the fuel under half level the car starts to fuel cut in hard corners. i know i need a surge tank but the leak is normal too?
