Well, I don't know about those numbers, but the hose (which seems to run 
in two sizes, little and bigger) should be easy and cheap to get.  I buy 
mine from Atlantic Imported here in NH-USA (on the vendor list at the 
website, with any luck).

If your dealer is friendly they might actually be an ok source, but I've 
never priced it that way.
