1) Drill and tap the trigger elbow (F) and the inlet valve end cap (G). You will need a 21/64 drill bit and a 1/8-27 NPT tap.

2) Wrap the threads on both of the tank valves and screw them in.

3) Wrap the 3/4 MT on (F) and (G).

4) I ground off the end rim on the valve extender so that the plunger could be pushed down flush. Then, attach it to the valve on (F).
