Cut the end of the line slightly conical and push harder.
Without any park tool or metal pin. The end need to be maximum flexible.

Hard job, but you will get it.

I've used some 1200 grade sandpaper to reduce the tip volume and then some Wera pliers close to the hole to push it. Quite easy, from the first try...
