Scheme 21: Tools and materials

A - Fuel transfer unit (This tool has been tested and approved by PORSCHE.); see Workshop Equipment Manual 3.2.2. "WE 1262"

B - Fuel nozzle - special accessory (This can be used to refuel the vehicle. The fuel nozzle switches off automatically as soon as the fuel tank is full.); see Workshop Equipment Manual 3.2.2 "WE 1262"

C - Porsche adapter (This adapter fits 8-mm to 10-mm fuel lines (986; 996 and Cayenne.); see Workshop Equipment Manual 3.2.2 "WE 1262"

D - Connecting piece between Porsche adapter and suction line (This is screwed into suction line E and connected to the Porsche adapter.); see Workshop Equipment Manual 3.2.2 "WE 1262"

E - Suction line with venting device (Always attach venting device (rubber taper with transparent hose) to the filler neck. This minimises the amount of escaping fuel vapours.); see Workshop Equipment Manual 3.2.2. "WE 1262"

ohne Bezeichnung - Adapter adapter P 9479 (For controlling the fuel pumps); see Workshop Equipment Manual, Chapter 2.2.2

Scheme 22: Using equipment

1 - Air connection (connection for unlubricated/oil-free compressed air)

2 - Fuel tank (capacity: 110 litres), (Tank can be changed. The scale at the side starts at approx. 10 litres. Other markings are shown in 5-litre steps.)

3 - Pump reversal (This allows you to change the direction of the pump from the fuel feed direction.)

4 - Operating pressure display (Displays the set operating pressure of the pump. The value cannot be more than 6.5 bar.)

5 - On/Off switch (For switching the pump on and off.)

1. Connect the fuel hose -1- to the changeover tank. Connect the venting device (transparent hose) to the changeover tank. Then attach the pneumatic stop switch -3- to the tank and tighten the two knurled nuts. (Scheme 22)

2. Connect the suction hose (or fuel nozzle) to the connection -1- and then connect the venting device -2-. (Scheme 22)
