I've been replacing all of my 11 year old fuel hoses with braided cover hoses and decided to do the flow guide valve vapor hoses for a consistent appearance. My valve cover breather hose was already a OE braided unit but I gave it quick inspection. Uh Oh - big crack at one end, time to replace it as well. A visit to MSA showed me a repro unit for (choke!) $90! 😲 So it was back to Belmetric for possible options. The valve cover fitting is 16mm in diameter but Belmetric only has 14mm and 17mm hose
