Review on 🏎️ Enhanced Performance: Muge Racing Universal Oil Catch Can Tank Kit with Breather Filter and Fuel Line - Aluminum, Black (Blue, 400ml) by Trey Michaels

The fittings included are not pipe threads. They are metric machine threads with an O-ring. I had to re-tap the hole to accommodate a 3/8" NPT fitting. The mounting methods are somewhat flimsy due to vibration and unreliable for use in a race car or motorcycle. The design is good with a variety of bleeding or back to engine options. If there were other ways to mount it to the vehicle I wouldn't have to worry about breakage, I could live with metric fittings.
