hanging outside propane stove/ hook to the quick fitting

part of the issue is there's low pressure and high pressure stuff. If you have a stove that uses a small bottle, it has a different fitting because the pressure is different. I have a two burner stove that uses the small bottles and I was trying to figure out how to get a hose so I could use the quick connect fitting on the side and I gave up... They make the fittings different so you can't hook up the wrong pressure.
