The PT-22 fuel system consists of a single tank mounted forward of the front cockpit. Fuel is gravity fed to the carburetor through a fuel strainer. A fuel selector valve, located on the left side of each cockpit has three positions: "main", "reserve", and "off". The "reserve" section feeds fuel from the reserve portion at the bottom of the aircraft's only fuel tank. The fuel gauge consists of a sight gauge above the tank, visible to both pilots out the front of the aircraft. The oil system is a dry-stump type, with all oil stored in a tank located on the front side of the firewall in the upper section of the fuselage. Oil Pressure and temperature gauges are provided in each cockpit. Normal oil pressures range from 40 PSI (at idle) to a max of 125 PSI, with 100 PSI being ideal. Normal oil temperatures range from a minimum of 35 degrees C to a max of 75 degrees C, with 60-75 degrees C being ideal. The wing flaps are mechanically operated from a lever located on the left side of each cockpit. Adjustable elevator trim is provided via an elevator trim tab controllable from a handwheel mounted on the left side of each cockpit. In its original configuration, the aircraft was not equipped with an electrical system. Hydraulic brakes are provided for each wheel, controllable via the rudder pedals in each cockpit[9].
