[Vwdiesel] a need for vacumn update, which bleeder to use

[David Cook]

germanautoparts.com sells a Motive power bleeder that
I have and highly recommend.

However, you can also make one of your own out of a
weed sprayer.  Basically all you need is the weed
sprayer, another reservoir cap, and a way to attach
the bleeder to the reservoir cap.

I adapted mine to fit an air-cooled cap using a
replacement tire valve (one that uses a nut to attach
it to the wheel).  Just cut the end of the weed
sprayer off and attach it to the tire valve.  Remember
to remove the valve core.
