Fuel systems today are most commonly associated with the automobile engine. When the automobile's fuel
Gauge nears empty, the driver must stop and get gas or diesel. The fuel is pumped from the gas/diesel pump
Down the filler tube into the automobile's fuel tank. This is the storage area for the fuel and where it begins its
Journey to the engine. A sender that is mounted in or on the fuel tank monitors the amount of fuel in the tank.
This information is sent electrically through a relay and wiring to the fuel gauge.
When the engine is started, the fuel system is energized. Fuel is drawn from the fuel tank by means of the fuel
Pump which, on most late model autos, is mounted in the fuel tank, often alongside the sender. The pump
Is usually operated electrically from the vehicles battery.
