After reading this blog, I went to the car parts store and bought an oil can and scavenged a "push-on" connector left over from my pitot/AOA parts bin.
Threaded the "push-on" in place of the reservoir cap, with a tube dangling down to a bottle.
The oiler was connected to the caliper with clear hose left over from my manifold air pressure system.
Below is the "push-on" fitting next to the supplied screened cap of the reservoir.

Below, you can see the smaller diameter clear tube added so I wouldn't have to hold it tight against the fitting. (the original was a little loose and leaked unless I held it tightly up against the nipple.) This also allowed me to get the 1/4" wrench on the fitting with out sliding the bigger tube partially off the fitting...crucial to keeping air bubbles out of the system. I used a little safety wire to seal the 2 tubes together.

A couple of zip-ties insure that I don't make an even BIGGER mess.

Hope this helps.
