A real bummer that the part is taking so long to get here, on the upside the chances are that Nissan is also waiting for a fuel related part and the irony of that is if it's a post-2000 Nissan, chances are the part came from France (Renault) before going to Japan!
Did you mention the seal to them?
Fingers crossed for you that it lands soon and you're mobile again!
