Now I am not telling you to do this, but if it were mine, i would just twist the aluminum tube if ya can, as you only need to rotate a tad. NOS bottles have a specific way to rotate tube as per their tech support.

I thought about that but having no experience with how soft or brittle the tube is I am afraid it might break or kink if I twisted it 90 degrees.

 

I was thinking about this again and now that I am going to put a jerico in the car I wiil most likely not spray over a 250shot. So could I sell both 15lbs bottles and just put one 20lbs and a heater. Do you think that would keep up enough pressure?
