Could anybody give me some info as to what happens to the small breather pipe that runs from the filler neck alongside the larger (around half inch in diameter)pipe around the side of the fuel tank and I think it thenis supposed to go through a small grommet in the floor to the underside of the car. It looks as though it should have a hose connected to it but i didn't take a photo prior to disassembly(stupid me)and I am now unsure as to what it now does or goes. Can anybody help with an original photo or some info please.
