Open or Closed?

There is a small vent hose that goes from the passenger side of the expansion tank (on top of the gas tank), to where you fill the tank with gas - just below the gas cap. the vacume hose attaches to a small metal tube under the gas cap. this metal tube where the hose attaches to is open. But on my car, the other end (by the gas cap) has been closed - like it had been crimped on the top and bottom. Is this end of the tube supposed to be closed? Are all 914's like this? Mine is a '73 1.4L.
Thanks in advance for your replys.

I meant to say 1.7 L.

Your discription is a little vague. The vent hose running from the fuel tank to the expansion tank should be open. It is the only vent the fuel tank has. If not vented, several problems could arise none of which are good.

J.P.,
Thanks for your reply. I'm refering to the metal tube attached to the filler section just under the gas cap. The passenger side of the metal tube (which is only about one and a half inches long) that the small rubber hose attaches to, is open. However, the other end, which ends just under the gas cap, that nothing attaches to, is closed. IS YOURS LIKE THAT? ARE ALL 914's SUPPOSED TO BE LIKE THAT?

My 73 2.0 is the same way. the little metal tube is not completely crimped off though (yours should not be anyway). it is crimped just enough that it looks that way when you look at it from above. I do not know why it was done that way other than to keep volumes of gas from going through (since its purpose is for vapors only).

WJDUNN3,
Thanks for checking your car for me. You are probably right about the gas cap end of the tube being partially closed so any spilled gas would not go into it. THANKS AGAIN!
