1. Preparation

Tools Required: Socket set, screwdrivers, fuel pressure gauge, OBD-II scanner, multimeter, safety goggles, gloves.
Disconnect the vehicle's battery to prevent electrical shock.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.

2. Remove the Fuel Pump

Sub-steps:
1. Access the fuel pump by removing the rear seat or accessing the fuel pump access panel in the trunk.
2. Disconnect the electrical connector from the fuel pump.
3. Remove the fuel lines connected to the pump (use caution, as fuel may spill).
4. Unscrew and remove the retaining ring or bolts securing the fuel pump module.
5. Carefully lift the fuel pump assembly out of the tank.

3. Inspect and Replace Components

Sub-steps:
1. Inspect the fuel pump for signs of wear, such as cracks or leaks.
2. Check the fuel filter and replace it if clogged or dirty.
3. If replacing the pump, ensure the new pump is compatible with the Volvo XC90.
4. Install the new fuel pump into the assembly, ensuring proper seating.
5. Reattach the retaining ring or bolts to secure the pump in the tank.

4. Reinstall the Fuel Pump Assembly

Sub-steps:
1. Reconnect the fuel lines to the fuel pump, ensuring they are properly seated and secure.
2. Plug the electrical connector back onto the fuel pump.
3. Position the fuel pump assembly back into the tank and secure it with the retaining ring or bolts.
4. Replace the access panel or rear seat.

5. Test the System

Sub-steps:
1. Reconnect the battery.
2. Install the fuel pump fuse back into the fuse box.
3. Turn the ignition to the ON position (without starting) to prime the fuel system and check for leaks.
4. Start the engine and monitor for proper operation.
