Thanks..

The trick on the cap entrance holes is to make them just a bit smaller than the hose.. that way, when you press the hose into the hole, there is no need for any gaskets as the hose will self-seal just from being oversize.
Another trick is to use a gas tank clunker from a chain saw or weed wacker on the end of the hose.. this keeps the hose on the bottom and filters out any dirt in the fluid.

I use a nipple for the cuff bulb so that I can use the same bulb for both the jar and the master cap when brake bleeding.. Works great on both systems .. you can find the pump at any yard sale for a couple of bucks..they usually even come with a stetoscope.so that can come in handy too...
Another trick on brake bleeding is to put another clear hose on the caliper bleeder draining into an open container.. this allows you to see any air bubbles in the drain line so that you know when you are done.. also lets you monitor fluid color.. I usually put a loop in this line so I can watch the air pocket/bubbles flow rate better..
