This model leaks @ the hose to the stem, & is fixed by replacing the washers (guts) by screwing on a LP gas nipple at the stem base..A longer than stock hose has enough flex the pivoting parts are not needed... The threads are close (not perfect) so gently torque.. This is a one time deal so I used Through the Roof clear seal haveing a better bond as silicone or tape on the threads...This classic is so worth saving over the current:: plastic body/ junk valve can't beat brass..
