Why build one?  You can buy them brand new on ebay for $40.  Do a search on pressure bleeder.

I'm planning to build a pressure bleeder to hopefully resurrect my clutch.
I've read numerous posts and web articles on these things, including both
a wet and dry approach (pumping fluid or just air). I'll probably try the dry
approach first to reduce possible mess.

My question is this - one article mentions that you're forcing fluid past the
master cylinder seals, which is something I had been wondering about.
Isn't there position in the piston stroke where fluid is allowed to enter the
cylinder? I imagine there must be, and if so, what is this position? It would
seem the resting positon would be the only way it could work. So doesn't
this mean the pressure bleeding doesn't actually force fluid past the seals
as long as the pedals remain in the up position?

Also, the same article mentions clamping the hose leading to clutch master
cylinder (not a Vanagon, but similar I guess) to avoid leaking at this hose,
since it's not designed for pressure. I'm thinking of trying 10-15 psi at most
and watching carefully for leaks. Any other tricks or tips?

Thanks.Shawn Wright
