oh ok, umm i dont knwo, maybe couldnt you get the tube from like home depot? i am not sure about the gas cap. you could always get one from a dealer and then modify it or something to make it work. or check EMPI. they are only VW's

Try this link and scroll down to "Fender Filler Kit". I think from your description, this is what you are asking about. Hope this helps.
