1968 Dodge Dart GT Sleeping Beauty?

I am getting close to having all the interior wrapped up. Remote side mirror is due next week. Other than carpet being a major item, I am in the home stretch.
Wiring harness is 90% complete. So I am making a mental list before the engine transmission drop. I need brake lines and a gas line.
I have tried to blow out the original line. It looks great and I wanted to reuse it
I have tried multiple times to clear it with my air compressor.

It finally broke open. 10-15’ across my floor and up to 10’ on the garage door. Foul sticky smelly old gas. The Dart was up in the air!
