The fuel filter on the Nissan Navara NP300 is typically located under the vehicle, near the fuel tank. It is usually a cylindrical-shaped component with two fuel lines connected to it.
2. Disconnect the Fuel Lines
Using a fuel filter wrench, carefully loosen the fuel lines connected to the filter. Be prepared for some fuel to spill out, so use rags or paper towels to catch it.

Connect the fuel lines to the new fuel filter and tighten them using the fuel filter wrench. Ensure the connections are secure to prevent fuel leaks.
6. Prime the Fuel System
After replacing the fuel filter, it’s essential to prime the fuel system to remove any air that may have entered during the process. Turn the ignition key to the “On” position without starting the engine. Repeat this process several times until the fuel pressure builds up.
