Tools and materials

Information

1. Prepare fuel transfer unit for draining fuel.

1.1. Connect the fuel hose -1- to the changeover tank.
1.2. Connect the venting device (transparent hose) to the changeover tank.
1.3. Attach the pneumatic stop switch -3- to the tank and tighten the two knurled nuts.
1.4. Then connect the suction hose at the connection -1-.
1.5. Connect the venting device -2-.

2. Connect the earth cable.
When using the pump, always make sure that the earth cable is connected to the vehicle. Use an unpainted metal part (e.g. the catch bar) for this.

INFORMATION: Fuel can be removed directly through the fuel filler neck on older vehicles or vehicles from other manufacturers by removing the connecting piece.

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:
Fuel can be drained using the following methods:
- At the installed fuel level sensor via the adapter.
- Directly from the tank with the fuel level sensor removed.

1. Drain the fuel.
1.1. Drain fuel at the installed fuel level sensor.

1.1.1. C2/RoW variant: Disconnect fuel line. Collect escaping fuel with a cloth.

1.1.2. C2/USA variant: Disconnect fuel line. Collect escaping fuel with a cloth.

1.1.3. Attach Porsche adapter to the adapter. Twist top and bottom part of adapter in opposite directions until it is tight.

1.1.4. Screw the connecting piece into the suction hose and tighten hand-tight.

1.1.5. Connect suction hose at the fuel level sensor.

1.2. Drain fuel at the installed fuel level sensor.
1.2.2. Disconnect connecting piece from the suction hose.
1.2.3. Insert suction hose into the tank in order to drain fuel.

1.3. Drain the fuel.
1.3.1. Set changeover lever to "Drain".
1.3.2. Switch on the transfer unit and drain the required amount of fuel.
