* In-tank fuel filter: This is located *inside* the fuel tank. It's not easily accessible without dropping the fuel tank. This is usually the primary filter and the one that requires the most attention.
* Secondary (Engine Compartment) Fuel Filter: There's also a secondary filter, often a spin-on type, located in the engine compartment. The exact location can vary slightly, but it's usually somewhere along the fuel line between the fuel pump (in the tank) and the fuel rail on the engine. Look closely along the frame rail, near the fuel lines. It might be close to the firewall or further along the line.
Because of the in-tank filter, replacing the filters usually requires professional help unless you're comfortable with fuel system work. Replacing the in-tank filter involves working with fuel, which is highly flammable and requires safety precautions. The secondary filter is easier to replace, but a messy job is still possible. Always follow proper safety procedures when working with fuel systems. If unsure, a mechanic should handle the work.
