So I'm trying to fix this burner someone made and the valves that let propane out don't seem like they are made correctly to me. As you can see the burners are about 6 inches away from the valve and it's just a hollow tube to let propane in. I feel like the valves should have a pipe running to the burner instead of just pressed against it. Any input will be greatly appreciated. I'm new to this forum so hi everybody.
