Is the input line the one that is a rubber hose then goes into a solid line? I am done, and I did NOT remove that one. That is the only one that I did NOT remove. I removed the small line on the bottom of the regulator and the one that is on top of the regulator. The one that is on the top is a short one. Is that the input?
Thanks
David

P.S.
Why shouldn't I disconnect the INPUT line if I didn't?
