FUEL DELIVERY SYSTEM – V8
DESCRIPTION AND OPERATION
19-2-7
Fuel Pump
Should the fuel pump electrical connection need to be disconnected, it is imperative that the ignition should be
switched off. If the ignition is on in any position the fuel gauge will memorise its last needle position prior to power
down. Once power is restored the gauge will display the last remembered position regardless of the actual level of
fuel in the tank. This will result in incorrect fuel gauge readings if the fuel tank has been drained and not filled worth
exactly the same quantity of fuel that was removed.
Injectors
An electromagnetic, top feed fuel injector is installed in each cylinder inlet tract of the inlet manifolds. A common fuel
rail supplies the injectors with fuel from a returnless fuel delivery system. The fuel in the fuel rail is maintained at a
pressure of 3.5 bar by a pressure regulator incorporated in the fuel filter unit on the side of the fuel tank. A Schraeder
valve is installed in the fuel rail, to the rear of injector No.7, to enable the fuel pressure to be checked.
