Functioning
Fuel is pumped from the tank by a roller cell pump through the fuel filter to the fuel rail at the end of which there is a
fuel pressureregulator. To maintain the differential pressure constant injector, despite variations in intake manifold by
depression load, the pressure regulator determines the difference between the pump pressure and that the intake
manifold. Excess fuel back to the tank, the continuous flow keeps the cold fuel and prevents the formation of fuel vapor
pockets.
The fuel pump is lubricated and cooled by the fuel flowing into the engine, including the brushes and through the
armature. It is therefore
important that the pump will never start without an adequate level of fuel in the fuel tank.
The fuel filter retains fuel impurities. It is important to prevent blockage of the fuel pump and injector nozzles
measure.
Resistance Fuel Pump = 2.7 + 0.1 Ohms
Function
Removing fuel from the tank, for propel fuel lines to the injector rail
and maintain a constant pressure in the system. The fuel pump also
needs to ensure that a high level of fuel flow through the fuel lines and
thus maintain a constant delivery pressure of fuel.
