Solution

1. Preparation

Gather tools and parts.
Tools Required: Fuel pressure gauge, socket set, wrenches, safety goggles, gloves, shop towels.
Parts Required: New fuel filter compatible with Renault Clio V.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Relieve Fuel System Pressure

Locate the fuel pump fuse in the fuse box and remove it.
Start the engine and let it run until it stalls to relieve any remaining fuel pressure in the system.
Turn off the ignition and disconnect the battery (negative terminal).

3. Remove Old Fuel Filter

Identify the location of the fuel filter (usually along the fuel line).
Use wrenches to disconnect the fuel lines from the filter, being cautious of any residual fuel.
Remove the mounting bracket or clamps securing the fuel filter in place.

4. Install New Fuel Filter

Position the new fuel filter in its mounting bracket or clamps, ensuring the flow direction matches the old filter (usually indicated by arrows on the filter).
Reconnect the fuel lines securely, ensuring there are no leaks.
Reinstall the fuel pump fuse and reconnect the battery.

5. Test the System

Turn the ignition to the ON position (without starting) to allow the fuel pump to prime the system. Check for leaks around the fuel filter connections.
Start the engine and observe its operation. Ensure it runs smoothly without any stalling or hesitation.
