I have the old school blue bottle that I took out of my se-r. I've been out of the seen for a while so is it okay to use or should I be looking at getting a newer kit. I was running dry before but i have all the parts to run wet on the z. If I get a new lit will my NOS bottle fit a zex kit? I have 2 10lbs bottles.

 

The bottles are the same both of them have a -4an outlet
