a few years back i cobbled a similar bleeder together since i wanted to
try this technique and compare it to my mighty vac bleeder.  specifically
i made to to bleed the rear wheels and clutch slave.  since i don't like
having stuff/tools around that can't do multiple functions i designed my
bleeder to use my bicycle track pump.

for the reservoir cap i used a scirocco/golf/jetta cap that i had on hand.
these have a fluid level sensor in the top and you can punch it out
leaving you a hole to put your fitting through.  i made my cap with a
quick disconnect on top so that it stores nicely in the toolbox with the
hose coiled up next to it.  i didn't want to deal with the kinky clear
poly hose so i used a heavier black rubber pressure rated hose that the
hardware store had on hand.  it is just a little larger than the clear
poly hose.    again the heavier rubber hose coils nicely and lays flat in
the toolbox when not in use.

so with this set up i can have the floor standing pump right next to where
i am working give it a pump and crack the bleeder.  just like the mighty
vac the only thing i have to go back up front for is to fill up the
reservoir.  just don't pump it up to too high of a pressure those little
rubber grommets that go between the reservoir and the master cylinder
aren't pressure rated :), and will start to leak.

the other thing i like about my set up is that if you are traveling and
already carrying the bike pump along you can pack the small coil of hose
and the cap and you have a small package road ready brake bleeder should
you need it.

mentioned in the recent posts about clutch slave cylinders. This should
help the bleeding procedure if like me you never have anyone around to
pump the pedal.
