gravity bleed the slave cylinder. then use a brake bleeder pump to pump fluid into the slave cylinder's bleeder valve. you will have to use a tool or turkey baster to remove the excess fluid from the reservoir and you pump the bleeder to prevent it from over flowing. do not reuse this fluid.

Simply push the hydraulic line back into the quick release fitting. When it is pushed all the way in you will hear a "snap" then it is locked in.
Actually , the clutch on your 1999 Ford Mustang is operated by a cable , it's not a hydraulic operated clutch so it doesn't use any fluid * if you want to adjust the clutch - without the engine running put it into 1st gear - GENTLY , using your foot , pull the clutch pedal UP until it stops - SLOWLY push the clutch pedal DOWN ( you will hear a click if the clutch needed adjusting )
Ford has used hydraulically operated clutches in the F250 for a long time. You don't adjust them. You could bleed it, if the clutch feels soft or spongy.
