Draining And Filling Fuel
Tools and materials
Item A - D:
Item E:
Using equipment
No. 1 - 5:
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.
2. Connect the suction hose (or fuel nozzle) to the connection -1- and then connect the venting device -2-.
3. When using the pump, always make sure that the earth cable is attached to the relevant vehicle. Use an unpainted metal part (e.g. the catch bar) for this.
NOTE: Fuel can be removed directly through the fuel filler neck on older vehicles or vehicles from other manufacturers by removing the connecting piece.
Draining fuel
WARNING:
Danger of fire.
- Keep clear of ignition sources.
- Do not smoke.
- Danger of fire due to naked flames and sparks, e.g. during welding or grinding work.
- Danger of fire due to escaping fuel, e.g. on hot engine components or due to electrostatic charge.
- Danger of fire due to hot exhaust system. Always allow the exhaust system to cool down.
- Secure the vehicle, e.g. with a warning sign.
- Change any clothing soaked with fuel immediately.
- In case of fire, use CO(2) or dry powder fire extinguishers.
CAUTION:
- Please observe general warning notes and working regulations.
- The tank can only be drained using the fuel pumps.
- It is not possible to extract fuel via the fuel filler opening and doing so may cause damage.
NOTE: All windows should be opened for better ventilation in the passenger compartment.
1. Fold rear seat forwards.
2. Fold up the retaining brackets of the right belt anchor. To do so, undo the three fastening screws and fold up the bracket with the belt anchors. Do not use the fastening screws again.
3. Undo the right cap. To do so, cut out the carpeted floor along the perforated lines using a carpet knife and fold it over. Then unscrew the four fastening nuts and remove the lids. View shows both lids.
4. Reduce the fuel pressure in the fuel line. To do so, screw down the protective cap on the fuel gallery and carefully press the valve. Collect emerging fuel with a cloth.
5. Carefully pull off the fuel line -1-. Collect emerging fuel with a cloth.
6. Connect earth cable to the vehicle.
7. Attach Porsche adapter to the connection piece. Twist top and bottom part of adapter in opposite directions until it is tight.
8. Screw the connecting piece into the suction hose and tighten it hand tight.
9. Connect the connecting piece to the adapter.
10. Open lid of central electric box. To do this, loosen the four fastening screws.
CAUTION:
Risk of damage
- Porsche adapter can slip from the tank connection.
- Only switch fuel pumps on after the extraction pump has been switched on.
- Always set extraction pump to suction mode -never refill mode- when the vehicle pump is running
NOTE:
- Use special tool 9479 from the measurement tool box to activate the fuel pump.
- Alternatively, adapters 26 and 25 can be connected and the fuel relay can be bridged. A fault is stored in the engine control module during this procedure.
11. Remove fuel pump relay -1- and -2-. The pump can be activated by bridging the relevant contacts. The contact assignment is printed on the corresponding relay. No faults are stored in the engine control module when special tool 9479 is used. Both pumps should be activated. As soon as the tank is empty, fit the fuel pump relay again and close the electric box.
12. Carry out any necessary repair work on the tank. Please observe the warning notes from chapter.
13. Fit all connections (fuel lines, ventilation tubes and electric plugs).
14. Fit lids. Tighten the four fastening nuts to 10 Nm (7.5 ftlb.). Refit carpeted floor and fix with double-sided adhesive tape.
15. Tighten the fastening plates of the belt anchors. Use three new fastening screws for this and tighten to 20 Nm (15 ftlb.).
16. Fold rear seat down again.
17. Refuel the vehicle.
