How do I insert the lines into the booster without leaks?

This has turned out to be the job from hell.

Not mechanically gifted, but have managed to replace both units for the ABS system.

When I open the door and the pump runs a tiny bit, fluid leaks from 2 of the lines connected to the master cylinder. I have bent the lines too many times, but I remember they were also difficult to remove initially as well. Spent all day working on it, I'm not sure what to do. All the YouTube videos I've seen make no mention of complications.

Bought the parts new from Olathe Toyota.

Any guidance is appreciated! I'm new here, so if this isn't the appropriate forum I can move as well. Thank you.
