Now I understand. You need the valve for off-board starting. All my jets have onboard gas, so it's very easy to just set the plastic barb into the Powermax can and pull it out when it is nearly full.

How ro i install these valves on my powermax can.? Tried to do itntoday and got propane everywhere. Should the can be upside down? Or just srew in fast. Had it all the way seated but was still leaking

Top of valve----part with trigger ,, rotates.. Loosen until ,pin that goes,into can not sticking out.
Push threaded ring on to can .screw on square part of valve,tight to top of can.
Then screw ,top of valve, with trigger clockwise untill pin goes in to gas can.
Bottom of valve {part with threads},seals can .

Tried that. Pin does not go up!! Here are a few pics..

Johnny, I replied on your other thread. You are missing a piece from the trigger valve.
