I just went out and checked. I have a small red high pressure regulator on the passenger (door) side and a regulator/auto change over on the driver's (ODS) side. They are different. The door side red one reduces the pressure since the tank on that side is farther away and is required for safety. It does not regulate the gas for use by appliances. That function is done by the auto change over regulator on the ODS side.
