Cracking of the lines will result in a leak.
As far as right away, no one can say without seeing the lines. Cracking of the outer skin is not abnormal. In your case, I bet the connection is what leaked and caused the fire. It has a seal inside that if the line is distured, it will leak.
The lines are built for pressure. The pressure is what went by the seals and caused this situation.
And by the way, the lines do not need to be removed or moved around to do the air filter.
