vw rule 19 Posted February 15, 2015 Hello Craig, that does sound as though the hose you've spoken of is perished. VW main dealer's were stocking this hose back along, as I purchased one with a ISV 3 or 4 years ago. The part number for the small elbow hose is I think 027-133-997AA The other larger ISV hose is part number 051-133-997A Hope this helps. Si Quote Share this post Link to post Share on other sites
