Propane modifications

I just mounted my Ragasco cylinders and want to add an auto changeover valve. That's the easy part. I also want to add two separate hoses from the changeover valve (presumably from a tee connected to the valve) - one that would go to a low pressure Coleman propane stove, and another hose that would go to a Yamaha 2000 propane powered generator with a quick disconnect at its end. I have been doing my research but just can't grasp which connectors/sizes are necessary.

Can anyone direct me to info that could be helpful? Thank you much in advance.
