FUEL TANK AND COMPONENTS

Description 1040A

1.2 8v, 1.4 16v

SUMBERGED PUMP ASSEMBLY - COMPOSITION

It consists essentially of:

• an electric fuel pump (1)
• a fuel filter (2)
• a float level level gauge (3)
• a pressure regulator (4)
• a mesh prefilter (5).

Fuel pump

The fuel pump is equipped with a permanent magnet electric motor (1) that controls the pump (2) and a terminal mount cover (3) that contains the electrical and hydraulic connections.

The pump stage is single, peripheral flow type with high performance under low voltage and temperature conditions.

The advantages compared to pumps that operate on volumetric principles are as follows:

• reduced weight
• limited size.

Fuel pump

Specifications:

• Capacity = 80 l/h
• Pressure 4 bar
• Valve control pressure = 5 bar

Fuel cut off function

There is no inertia switch on this vehicle; the fuel cut off function is managed by the Body Computer Node and by the Engine Management Control Unit according to the signals received by the Air Bag control unit via the CAN.

SUBMERGED PUMP ASSEMBLY COMPLETE WITH LEVEL GAUGE

The fuel pump is part of a single assembly with the level gauge and fuel filter. Components cannot therefore be replaced individually.
