LOW AND HIGH PRESSURE FUEL LINES Component Description



Item Description A LP fuel lines B HP fuel lines 1 Acoustic cover 2 Heat reflective and insulation sleeves The LP fuel line connects the HP fuel pumps to the fuel delivery line from the fuel tank and lines system. A quick release
connector at the start of the LP fuel line is held in a clip integrated into the LH (left-hand) ignition coils cover. P-clips secure
the LP fuel line to the rear of each cylinder head and to the RH (right-hand) side of the cylinder block. A heat reflective and
insulation sleeves are installed on the LP fuel line where it runs behind the RH exhaust manifold.
The HP fuel lines connect the HP fuel pumps to the RH fuel rail and the crossover tube. Two P-clips and a pipe clamp attach the HP fuel lines to the cylinder block and the RH cylinder head respectively. An integral bracket on the front HP fuel line is attached to a stud on the front-upper RH timing cover. An acoustic cover is installed on the bottom of the front HP fuel line.

RH fuel rail. The FRP sensor is screwed into a threaded boss in the fuel rail. A flying lead and three pin connector provides the interface with the engine harness.

The FRP sensor contains a steel diaphragm fitted with strain gages, which are incorporated into a Wheatstone bridge. The output from the Wheatstone bridge is processed by the ECM to derive a pressure value.
FUEL INJECTORS



The fuel injectors spray fuel from the fuel rail directly into the combustion chambers. The fuel injectors are installed close to
the center of the combustion chambers, between the inlet and exhaust valves and next to the spark plug.

The fuel injectors are a push fit in the fuel rails and the cylinder heads. On each fuel injector, a rubber O-ring seals the head of
the fuel injector in the fuel rail. A teflon ring seals the nozzle of the fuel injector in the cylinder head. A clamp locks each fuel
injector to the fuel rail. FUEL RAIL PRESSURE SENSOR

WARNINGS: Cleaning

Do not carry out any repairs to the fuel system with the engine running. Failure to follow this instruction may result in
personal injury.


Do not smoke or carry lighted tobacco or open flame of any type when working on or near any fuel related components.
Highly flammable vapors are always present and may ignite. Failure to follow these instructions may result in personal injury.


If fuel contacts the eyes, flush the eyes with cold water or eyewash solution and seek immediate medical attention.


Place the vehicle in a well ventilated, quarantined area and arrange ' No Smoking/Petrol Fumes' signs about the vehicle.


Wash hands thoroughly after fuel handling, as prolonged contact may cause irritation. Should irritation develop, seek
medical attention.


Do not carry or operate cellular phones when working on or near any fuel related components. Highly flammable vapors
are always present and may ignite. Failure to follow these instructions may result in personal injury.
CAUTIONS:


Before using the cleaning fluid, protect all electrical components and connectors with lint-free non-flocking material.
Make sure that all parts removed from the vehicle are placed on the lint-free non-flocking material.
Make sure that any protective clothing worn is clean and made from lint-free non-flocking material.


Make sure that clean non-plated tools are used. Clean tools using a new brush that will not lose its bristles, prior to
starting work on the vehicle.


Use a steel topped workbench and cover it with clean, lint-free non-flocking material.


Make sure the workshop area in which the vehicle is being worked on is as clean and as dust free as possible. Foreign
matter from work on clutches, brakes or from machining or welding operations can contaminate the fuel system and may result
in later malfunction.

1. Using a new brush that will not lose its bristles, brush the components
being removed and the surrounding area.

2. Using a pneumatic vacuum gun, remove all traces of foreign material.
