Saab: 93 Saab 9000 gas leak, vent hose, saab dealer

Question
What is the part called, I would call it a fuel tank vent hose, that is a "Y" shaped hose close to the top of the tank?  Mine is cracked and needs replacing.  Leaks if you completely fill the tank and since leak, the engine quietly dies when coming to a stop only when the tank is low on fuel.  I need to order one but cant seem to find the correct name therefore correct part number.  Thanks.

Answer
Olin:
 Sorry, but as stated in my profile, my hands-on experience is limited to the 900 series only. However, may I can suggest that you explain the problem to the "parts man" at a SAAB dealer;  they should certainly be able to help.

  Hope this helps,
