Fuel Tank; Fuel Pumps - Aston Martin V8 Vantage Workshop Manual

Fuel Tank

The fuel tank incorporates a single filler neck and check valve, internal fuel pump, internal fuel filter, a sender unit and an
'on board refuelling vapour recovery' system.

Fuel Pumps

The modular fuel pump is immersed in the base of the fuel
tank. The pump can deliver up to 150 litres/hour. The in-
tank fuel line connects to the external line using a quick-fit
connector in the base of the fuel tank.

During normal running, pressurised fuel from each fuel
pump passes from the tank, through an 3 micron in-tank fuel
filter to one of the two fuel rails on the engine.
Fuel temperature is measured on the primary fuel rail. If fuel
temperature becomes excessive, the fuel pressure is
increased to prevent fuel vaporisation (boiling).
Fuel pressure is measured by sensors on each fuel rail. The
fuel pressure to each rail is regulated as required by
continuously changing the run speed of the associated fuel
pump. Maximum pressure in the system is limited to 5.3 bar
by in-tank pressure regulators.
A constant head of fuel is maintained in the fuel pump
modules to ensure that the pumps cannot run dry in a 'low
fuel' situation.
