I have an 18/44 FasTrak that's about due for new oil and filters in the IZT's. Can someone give me a source for the plastic hose barb that supports the IZT breather tube? Another possibility is that I could order it from Hydro Gear if I can get the Hydro Gear part number. It is not a standard NPT fitting. One of these broke when I checked and added oil a while back, evidently cracked from vibration during use since it broke as I was removing it by hand. Hustler only sells these barbs as part of the breather hose assembly at $32 plus tax each. That makes for expensive oil changes. It's a great machine and this has been my only problem with it in almost 2 years of use.
