 The first thing you need is a garden sprayer. I bought mine at Menards for about $9

.

I also got a $5 air pressure guage, drilled a hole for it, added an o-ring and screwed it in place with a brass nut on the back side.

No leaks and on to the next step. Remove the wand after the switch,

add a Watts # A-732 pipe coupling, screw on a Watts A-96 hose barb adapter. Push on some wtts svfd10 5/16 clear tubing. Get the cap appropriate for your brake system. Our Firstgens have a cap with a rubber gasket that has an air gap behind it. That way as the fluid level drops over time there is no vacuum to suck air into the system.

If you have more modern brakes the cap has either a small hole or a groove to allow air in and prevent the vaccum problem. You need to seal that with some kind of sealer. I used form a gasket from Permatex. Dill a hole in the cap to accept the barb appropriate for the tubing  you bought. Add some o-rings or rubber gaskets to each side and you are done.

When I get a decent weekend day I'll show you all how it works.
