o-ring

I recently rebuilt my HPFP and instead of putting it all in my engine thread I figured I would make a dedicated post. UPDATE: Corksport now sells a kit for this as well. They are pretty much the same thing so whatever you can get, get that one. and their GUIDE This is actually pretty simple...

I can't take credit for pulling the basic part number list together but I did measure a few and make sure our friends at McMaster-Carr had standard Buna-N and Viton versions available. From my post on the other forum.... Links take you to McMaster-Carr HPFP housing ID = 32mm T = 2mm Buna-N...
