🔩 Torque settings
Values can differ between engine variants — check the code stamped on your block.
| Torque | Fastener / step |
|---|---|
| 110 Nm (81 lb-ft) | Start locking ring and tighten using wrench |
| 110 Nm (81 lb-ft) | Tighten locking ring using wrench |
ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.
📋 Procedure
- ⚠ Do not bend float arm of fuel gauge senderG when installing. — Insert fuel delivery unit (without suction-jet pump) into fuel tank.
- Install suction-jet pump (B) and reconnect coupling (A). Check coupling is secured properly by pulling.
- Insert delivery unit into fuel tank.
- Reconnect coupling (A). Check coupling is secured properly by pulling.
- Connect fuel line (B) to fuel delivery unit.

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.
