I realized I needed a whole new plug and had some difficulty finding one.

The thread pitch on the main air fitting on the bottom plate did not match original. Luckily, the original was easily interchanged with the plate on the new part. Be VERY careful when removing the 4 attaching screws as the main switch will fall apart. Take old one apart first to see what happens, and then also drill holes in old one very slightly larger for the new screws to pass thru.

Ordered because I had a air leak coming out of the vent tube going into the pressure switch. Still have the same leak with the new pressure switch. Not sure why , or what is causing the leak.
