Looks like you have most of it there. What exactly is not working in it? I will tell you one thing, where you took your vertical regulator off is not how it should come off. The whole body should stay connected to where to the threaded part. Most will just twist off but sometimes you have to use a wrench on that lock ring to get it loose. Just shoot me a PM with anything you need help with.
When your talking about decreasing the pressure. You mean on the maxflfo right? The little gauge on mine kept going to 250+ and then spiking down. It would keep doing it. I unscrewed it all the wa and went from there.
