In 2019, we noticed a strong gas smell outside our 1989 WB 40 near the LP bay. Luckily, I was able to quickly locate the leak with some soapy water in a spray bottle. The leak was coming from a rubber gasket between first and second stage of the regulator ''(See Picture A)''.  The regulators that Blue Bird originally installed are obsolete, so I replaced mine with a '''FISHER''' '''R232A-BBFXA 1/4 INLET 1/2 OUTLET''' ''(see picture B)'' '''t'''hat I found on eBay. Keep in mind that the life span of the diaphram in these regulators is around 20 years on the high pressure side, so if your coach is getting up there in age, you'll want to have a spare regulator onboard.

Make sure your replacement regulator is a TWO Stage that is able to handle tank pressure, since it can be as high as 235 PSI on a hot day traveling down the road.

The second stage regulator is made to have a high pressure regulator installed before it and the correct output of the second stage is 11-14 inch water column (~0.4 PSI).  Initially I was confused, since all the regulators look very similar to each other. Always check the tag on the regulator that you are going to install for proper information.  In my case, the trailing letters '''FXA'''  were important because they indicated the direction of the vent.  By code, vents are supposed to be pointing down when the regulator is installed.
