Solution

1. Preparation

Gather tools and parts needed for the replacement.
Disconnect the battery to prevent electrical issues.
Relieve fuel system pressure by locating the fuel pump fuse and starting the engine until it stalls.

2. Remove the Fuel Filter

Locate the fuel filter; it is usually found along the fuel line under the vehicle or in the engine compartment.
Use a socket set to remove any brackets or mounts holding the filter in place.
Carefully disconnect the fuel lines from the filter using a fuel line disconnect tool; be cautious of any residual fuel.

3. Inspect and Install the New Fuel Filter

Compare the old filter with the new one to ensure correct size and type.
Install the new fuel filter, ensuring the direction of flow is correct (marked on the filter).
Reconnect the fuel lines securely and reattach any brackets or mounts.

4. Reconnect Battery and Test

Reconnect the battery terminals.
Turn the ignition to the "on" position (without starting the engine) for a few seconds to prime the fuel system.
Start the engine and check for any leaks around the fuel filter.
