Zf5 swap clutch line issue with snapping in
 

Completed the ZF swap. I used the quick disco tool when disconnecting the clutch line on the Mazda tranny

When putting the clutch line on the zf5 it wont snap in!
Opened the bleeder valve and tried-no luck. The white plastic grommet is new. And I removed the old one from the zf5 and they look the same.

My truck is a 96 4.9 m50d 2 wheel drive. 8 foot bed reg cab
the ZF5 is a S42 manufactured in i believe mid-late 92.

What gives????

EDIT: WRONG SLAVE CYLINDER FORD CHANGED SLAVES IN 93 MY TRANS IS A 92 SLAVE IS WRONG CLUTCH LINE WONT WORK TRANS HAS TO COME BACK OUT FAIL
