1. Locate the fuel filter (usually near the fuel tank or along the fuel line).
2. Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
3. Disconnect fuel lines from the filter using a line wrench.
4. Remove the old fuel filter and replace it with a new one.
5. Reconnect the fuel lines securely.

Tools Required:

Line wrench
Fuel filter replacement

3. Clean or Replace Air Filter

Sub-steps:
1. Locate the air filter housing and remove the cover.
2. Remove the air filter and inspect it for dirt and damage.
