Installation guide - Replacing a fuel pump
General guidance for this part type - always follow your device manual- Fuel line disconnect tools
- Lock ring tool or brass drift
- Fire extinguisher nearby
- This is an advanced job: follow your vehicle's service manual, or have a qualified mechanic fit it.
- Keep the tank low on fuel before starting; it makes the job safer and lighter.
- 1Make it safe. Engine off and cool, in a ventilated area with no sparks or flames. Relieve fuel pressure as your manual describes, then disconnect the battery negative (-) terminal.
- 2Reach the pump. Many cars have an access panel under the rear seat or trunk floor; others need the tank lowered (see your service manual).
- 3Disconnect. Unplug the connector and release the fuel lines with the disconnect tools, catching drips with a rag.
- 4Swap the pump. Undo the lock ring, lift the old assembly out tilted so the float arm clears, and fit the new one with a new seal, lined up with the tank's locating tab.
- 5Prime and check. Reconnect everything, turn the ignition on and off a few times to build pressure, check for leaks, then start the engine.
This is general guidance for the part type, not a model-specific procedure. If the part does not fit without force, stop and recheck compatibility.
