1. A combination pressure regulator, comprising:
a regulator body having an inlet port on an exterior surface of the regulator body, an outlet port on the exterior surface of the regulator body, and a combined inlet and outlet port on the exterior surface of the regulator body;
a first pressure regulator including a first diaphragm, a first valve assembly movable by the first diaphragm, and a first biasing member that applies a first bias force to the first diaphragm to establish a first pressure regulator setting;
a second pressure regulator including a second diaphragm, a second valve assembly movable by the second diaphragm, and a second biasing member that applies a second bias force to the second diaphragm to establish a second pressure regulator setting different from the first pressure regulator setting,
wherein an input portion of the first pressure regulator is in fluid communication with the inlet port, an output portion of the second pressure regulator is in fluid communication with the outlet port, and entirely within the regulator body both of an output portion of the first pressure regulator and an input portion of the second pressure regulator are in fluid communication with the combined inlet and outlet port.
