Slave master cylinder problem!

So I was installing my new/used slave assembly. when I installed it and topped off the reservoir. Started pumping. Clutch had no pressure and no resisting when pushing the clutch. The pedal would be locked to the floor so you’d have to pump with hand. Still pumped like 50 times no difference no pressure. So I was trying to diagnose. And I decided to do the slave cylinder hose to see if liquid was being pushed. There was not. Then I decided to do the master cylinder cause if there’s no fluid in the slave then how could it build pressure to push the clutch fork. So here’s a vid of the slave cylinder and master cylinder being pumped. Id assume when the hardline is disconnected from the master cylinder it was leak uncontrollably but I’m not sure cause this is the first time doing this. Lmk if this is normal or not and what I should do. I was planning on gettting a new master cylinder or even replace the whole assembly.https://youtube.com/shorts/Y38a0kKPK...bGMCZmC6jLRldp

No visible leaks when everything was installed assuming it’s something internal. Any help is appreciated thank you

You started with a dry master cylinder. Read up on bench bleeding master cylinders.

Mine drains slowly just by opening the bleed valve. Keep air from being sucked in on the release.

So do I get my $5?
Or is the Slave Master not part of the "Manual Swap"?

Have you looked into the differences in the wiring and ECUs of manual and autos? If not, bleeding the clutch system may be the least of your worries. From my understanding, switching from auto to man not a "plug and play" deal.

It also is plug and play because there’s no wires that connect to the clutch. It’s it’s own separate system that doesn’t require any wiring the harness

I’ve also already installed everything to manual already. The only problem in my way from getting the car started and on the road is the clutch pedal/slave cylinder and or master cylinder
