We just purchased a 1996 Coleman Cheyanne and heading out for our first trip in a couple days. Our gas line runs inside and splits to an outside quick connection as well. I'd like to run our camp stove (https://gsioutdoors.com/selkirk-540-camp-stove.html) outside instead of the stove that came with the camper. I bought a quick disconnect hose (https://www.amazon.com/gp/product/B07SZL6H45/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1) but when I connect the hose no gas comes out to the stove. The propane tank is full and I tested it with our outdoor fire pit, works great. I checked the quick connect on the curb side under the trailer by depressing the plunger inside the connection and gas came out. The stove inside works as well. When I connect the hose to to the quick connect, no gas comes out. Must have purchased the wrong type of hose? Any clue which is the correct hose?
