2892421 - INTRODUCTION - FUEL TANK AND PIPES (GPOWER, Euro 3, BIPOWER)
The fuel system is "returnless", i.e. with a single pipe connecting fuel tank and engine. The return pipe, filter and pressure regulator have therefore been eliminated. The filter and pressure regulator are built into the pump assembly.This:
- minimises the possibility of the vehicle catching fire in case of an accident.
- reduces fuel vapour emissions to the atmosphere.

The dual operation fuel system (petrol and methane) consists of a traditional fuel system (Magneti Marelli IAW 49F) for petrol operation and a built in (OMT Tartarini) CNG fuel system for methane operation.The methane fuel system is described in subassembly 1042.The petrol supply system is "returnless", i.e. with a single pipe connecting fuel tank and engine. The return pipe, filter and pressure regulator have therefore been eliminated. The filter and pressure regulator are built into the pump assembly.
This:
- minimises the possibility of the vehicle catching fire in case of an accident.
- reduces fuel vapour emissions to the atmosphere.

The dual fuel system (petrol and LPG) consists of a combination of a basic conventional petrol system (Magneti Marelli IAW 4EF.G1) for petrol operation and a Liquid Petroleum Gas supply system (Vialle/Metatron) for LPG operation.The LPG supply system is described in subunit 1043.The petrol supply system is "returnless", i.e. with a single pipe connecting fuel tank and engine. The return pipe, filter and pressure regulator have therefore been eliminated. The filter and pressure regulator are built into the pump assembly.
This:
- minimises the possibility of the vehicle catching fire in case of an accident.
- reduces fuel vapour emissions to the atmosphere.
