I remember seeing these brake fluid pumps when I was a kid, think every gas station had one.
OK, last one.
This is from the famous Jimmyl, a good pictorial:

When doing the Factory method as outlined in the FSM, going from the R/F brake caliper to the Slave cylinder, to first power flush the brake system and the clutch to blow out any and all contaminates.
Maybe first use your wife`s Turkey baseter to suck out as much of the old fluid first.
When I swapped the 4-spd into our 85 300D, I power flushed the clutch with my Motive. I blew enouth fluid through it, there couldn`t possibly be any air in the system. still no clutch.
Used the FSM method, still nothing.
Used the oil can method, still nothing.
Even tried to gravity bleed it, but nothing would drip out.

I read where Gavin Leslie did this, and all was good.
Finally out of frustration, had my wife pump the clutch peddle, hold, open slave bleeder a few times, and it worked. what the....

although the peddle was down lower that I would have liked it, it worked and if it works, don`t further mess with it.
Since then I removed the transmission etc..... and am back to the bleeding problem. that was 19 months ago and the car has sat since then. but since the 240 drives..................... do need to flush the 240, so need to get at least one working back up car.
