It's regular DOT3 brake fluid. Bleeding is a pain in the butt. I use a MityVac hand-held vacuum pump, but I had to wrap teflon tape arond the threads of the bleeder screw to keep it from sucking air in past the threads. If you apply too much vacuum it will also suck air in past the slave seal.
The clutch hydraulic system is a closed system, there's not really any place for the fluid to go to. My first suggestion would be to pull the carpet and padding back under the clutch pedal and see if the fluid leaked out there from the back of the master cylinder. On the slave cylinder you can pull the boot off of the body of the cylinder and check for fluid there.
