I call it a continuous vacuum bleeder, but it's a homemade affair. I put what is called a vacuum ejector on the cap of a pickle jar and connect a compressed air line to it. I then have a line I can attach to a bleeder screw, and then it applies full vacuum for as long as I need it to, hands free. I saw one somewhere...forget where now, but just made a cheap copy. I use it for brakes, hydraulic clutches, etc. It makes things much easier when working alone.
Have you adjusted the master cylinder pushrod?
The MC, CSC, and Line are for a 93. The MC pushrod is non adjustable unlike the 84 and up. I wonder if I have to have a MC for a 84-86…..
