When the pedal is pushed it forces fluid past the relief valve and as soon as the pedal is released the valve shuts - so you can pump all you want as long as fluid is in the reservoir of the MC. You don't need pressure or vacuum bleeder pumps.
They are how I finally got my ERA bleed out. But I thought back in the early part of your thread that you had these on your calipers ???

Yes - you can see the Russell ones here:
Aftermarket Brake Kit Application Guide - Speed Bleeders - Russell Performance Products
They're widely available in parts stores, speed shops, etc. and come in a variety of sizes to replace bleed screws in OEM and after-market calipers. For Wilwoods you only need a pair for each caliper to replace the upper bleed screws - you can leave the lower bleed screws in place as you'll never use them anyway.
BTW, my rear lines were pretty much completely dry when I bled them, and I was astounded how many pumps it took of the brake pedal before I got anything out. The key message is it may take a lot longer than you think before you get all the air out. Brake fluid is relatively cheap - don't be afraid to waste some, and always start with the wheel furthest from the MC and work closer as you go (RR, LR, RF, LF - for LH drive cars).
