I went to turn on my refrigerator in the camper at the storage lot this afternoon. When I opened the bottle valve on the tank away from the regulator, the small in-line regulator started spewing propane from a small bleed hole. I turned the tank back off and went around to the other side bottle where the tank switch and low pressure regulator is. I opened it and all was well.
There is a high pressure (30 psi) regulator pressed onto the supply line. I assume this is to knock the pressure down from tank pressure to relieve stress on the long line going to the other side switch/regulator. A quick Google search doesn't show any supply lines with a high pressure regulator. The red writing in the center of the regulator on the 2nd pic says "30 psi"
Do I really need this and where can I get one?
