The best of these propane quick connectors are made by Marshall Brass Company and are available at Amazon, Menards, Camping World to name a few. You will need to do a trace to find out if your line taps in before or after the high pressure regulator at the tank. Our motorhome taps BEFORE the regulator so the rubber hose is a high pressure line with quick-release brass fittings. The BBQ grill has a regulator built-into the control knob.
