Sec. 36.22  Fuel-injection system.

    This system shall be so constructed that the quantity of fuel 
injected can be controlled at a desired maximum value and shall be so 
arranged that this adjustment can be changed only after breaking a seal 
or unlocking a compartment. Provision shall be made for convenient 
adjustment of the maximum fuel-injection rate to that required for safe 
operation at different altitudes (elevations above sea level). The 
governor, controlling engine speed and fuel injection, shall not 
directly affect airflow to the engine and provision shall be made to 
seal or lock its adjustment compartment. Filters shall be provided to 
insure that only clean fuel will reach the injection pump or injectors.
