Assembling The Fuel Measuring Tool

WARNING: This page is about a different car, the 2010 Porsche Cayenne, 2009 Porsche Cayenne, and 2008 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.

Information

The tool setup must be fitted with sealing rings (copper, aluminium, or plastic, etc.) between the individual components. The setup must be fully sealed.

ohne Abbildung - A stopwatch is required to perform to measurement.

Assemble the measuring equipment as shown in → Fig 1 .

Taking measurements

WARNING: Toxic substances

Danger of poisoning or suffocation
Danger of burns to the eyes and skin

→ Ventilate the work area well.

→ Never ingest or inhale.

→ Read specific information on the Hazard Sheet.

→ Wear personal protective gear.

→ Do not smoke, eat or drink in the work area.

WARNING: Highly inflammable or explosive materials

Danger of fire or explosion

→ Avoid contact with hot parts or sources of ignition.

→ Use suction to remove ignitable vapours.

→ Attach warning sign in a clearly visible position.

Information

Get a second worker to help perform the measurement if necessary.

Information

Place cloths underneath the line connection points to soak up fuel.

Pull off the fuel supply line -1- from the right connection unit.

  Information
  
  Position the measuring cup and the open end of the hose outside of the vehicle.
2. 2.2. Hold the open end of the hose from the measuring adapter 9705 -2- into a measuring cup with a volume of at least 1 litre.
3. 2.3. Set the stopcock to the 'flow' position.
Bleed the measuring tool.
1. 3.1. Ensure that the open end of the measuring tool is securely retained in the measuring cup.
2. 3.2. Fit fuses 13 and 14.
  Information
  
  Pressing the switch activates the fuel and pump and starts the fuel supply. This action bleeds the measuring tool.
3. 3.3. Set adapter 9479 switch to position "1" until fuel runs out.
4. 3.4. Empty the measuring cup of fuel.
Carry out the fuel delivery rate measurement.
Information
- The fuel pump must deliver at least 0.6 litres of fuel during the measurement period. Replace the fuel pump if this delivery rate is not achieved.
- The pressure gauge shows a fuel pressure of 2.5 to 2.7 bar during the measurement. This counter-pressure is generated by the pressure regulator on the measuring adapter 9705.
1. 4.1. Simultaneously set adapter 9479 switch to position "1" for 20 seconds and start the stopwatch.
2. 4.2. Set adapter 9479 switch to position "0" for 20 seconds.
  Information
  - The fuel pump must deliver at least 0.6 litres of fuel during the measurement period. Replace the fuel pump if this delivery rate is not achieved.
  - The pressure gauge shows a fuel pressure of 2.5 to 2.7 bar during the measurement. This counter-pressure is generated by the pressure regulator on the measuring adapter 9705.
3. 4.3. Measure amount of fuel in the measuring cup.
