  1. Dimension (a) is 1225 mm.
  2. Open tank flap unit.
  3. Clean area around fuel filler neck.
  4. Unscrew cap (1) for fuel filler neck.
  5. ⚠ Secure earth wire of fuel extractor to a bare metal part of the body. — Pull cotter off fuel extractorVAS 5190.
  6. Screw shaft piece (3) of fuel extractorVAS 5190 onto fuel tank filler neck (2).
  7. Push extraction hose of fuel extractorVAS 5190 into fuel tank until previously attached marking (arrow) on hose coincides with shaft piece (3).
  8. This opens flap (1).
  9. Drain fuel tank via filler neck as far as possible. [Note: There is a flap (1) in the fuel tank at the lower end of the filler neck. The flap must not be damaged by the extraction hose. Therefore push hose into filler neck only as far as marking (arrow).If the extraction hose gets caught on the non-return valve (1) when being pulled out, do not apply force to pull out the extraction hose.In this case, remove the fuel delivery unit and open the non-return valve manually. Ensure that your arm does not come into contact with fuel.]
  10. Pull extraction hose out carefully.

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
