I got a full set of steel brake lines for the Valiant from inline tube.

I was going to only install the ones that really need replacing, and leave the rest for some future large-scale disassembly project.

I was on a roll last weekend, and just disconnected all of them and began removing them when I realized that the one along the firewall goes under the engine harness, heater hoses, throttle cable, blower motor and wiper motor.

Is there a trick to getting this one in and out, or do I have to remove/disconnect all that stuff?

(like if I jack the front end high enough I can rotate the old tube counterclockwise and remove under the car, then rotate the new one the opposite way, only disconnecting a few things.)
