The upper ends of the yoke body include a bore ( ). A plunger ( ) is operative to slide through the bore. The yoke body includes an opening ( ) that is operative to receive a post valve ( ) of the tank. The yoke is operative to urge the post valve with the plunger into sealed engagement with a passageway ( ) in the lower end ( ) of each yoke responsive to the movement of a lever arm ( ) in pivoting connection with the plunger. A trigger lock ( ) is operative to lock the lever arm in an engaged position to prevent the yoke from accidently disengaging with the post valve.
