CG901

I have a 28 year old Heinzmann fire bottle (Halon) in my racecar. There are two lines going out to the front and back of the car feeding the spray nozzles.
I want to remove the bottle to gain access to the fuel cell. Can I just pull these lines?
See photos. Car is circa 1990. Thanks. See photos.

This is one of the lines out. I assume the seal has to be punctured to release the gas, so no problem removing this line?
