## What it covers

The portion of the aircraft fuel system other than selector valves, transfer valves, electric motor driven pumps used to distribute fuel from the tank outlet to the powerplant quick disconnect or up to the strainer unit. Includes the engine primer equipment, the switch that senses failure of a system pump, and the switch that automatically activates the boost pump. Typical parts are line, fitting, primer, nozzle, primer pump, actuating linkage for the fuel selector/shutoff valve, etc.
