- Chapter 2: Engine Fuel & Fuel Metering Systems › Basic Fuel System
During starting, the boost pump forces fuel through a bypass in the engine-driven pump to the metering device. Once the engine-driven pump is rotating at sufficient speed, it takes over and delivers fuel to the metering device ... specified pressure. The airframe fuel system begins with the fuel tank and ends at the engine fuel system. The engine fuel system usually includes the engine-driven pumps and the fuel metering systems. In aircraft powered with a reciprocating engine…

pump is illustrated in Figure 2-60. The impeller, which is driven at a greater speed than the high pressure elements, increases the fuel pressure depending upon engine speed. The fuel is discharged from the boost element (impeller ... high-pressure gear elements. A relief valve is incorporated in the discharge port of the pump. This valve opens at a predetermined pressure and is capable of bypassing the total fuel flow. This allows fuel in excess of that required…
- Chapter 14: Aircraft Fuel Systems › Small Single-Engine Aircraft Fuel Systems › High-Wing Aircraft with Fuel Injection System
High-Wing Aircraft with Fuel Injection System Some high-wing, high-performance, single-engine general aviation aircraft are equipped with a fuel system that features fuel injection rather than a carburetor. It combines gravity flow with ... fuel pump(s). The Teledyne-Continental system is an example. [Figure 14-14] Note: Fuel injection systems spray pressurized fuel into the engine intake or directly into the cylinders. Fuel without any air mixed in is required to provide…
