Mark is not making these any more, appears he hasnt made them for some time. I have a post in the FB world on the Tormach page where a fellow user posted a pic of a setup he made, 2 fittings and piece of tubing, pretty sweet. Ideal if you have upgraded and have a remote/external fluid tank. The remote capability of Mark's design was really nice if you still use the stock internal setup, but I am sure another version could be fabricated fairly easy. McMaster-Carr to the rescue.
