Had to remove the top plate which holds the manifold, the part that has the gauges and hose outlets on it. Then I had to remove the outlet tube using a 14 mm wrench. I had to put on the o-ring and nuts making sure they go in the right direction, the compression fitting has to go on a certain way. I then tightened the tube down. Replaced m anifold and replaced the top plate. I did some other things like checked the regulator. Made sure the cutoff was working right.

Removed plastic casing took off brass nuts installed new tube note of caution I planned on reusing the existing brass nut, o ring and compression nut the brass nut and o ring can be reised but you will have to get a new compression nut with collar once tightened it can\'t be reused and these fittings do not come with the new inlet tube.
