el can also clog the fuel filter. Many mechanics recommend that you change the fuel filter any time a tune-up is done on the car or truck - usually every 3 to 5 years - or any time a fuel pump has been changed. The fuel filter has a limited lifespan and requires regular maintenance. Serviceable in-line fuel filters have predetermined service intervals recommended by the auto manufacturer, so be sure to consult your owners’ manual.
If this maintenance is not kept up, and the filter becomes clogged, it can cause a restriction in fuel flow, making it hard for the engine to draw precious fuel. This can make the car hesitate or jerk during acceleration or can make it stall out. If the problem gets worse you might not be able to start your car at all. A clogged fuel filter can also cause harm to the fuel pump.
Can I Replace a Fuel Filter Myself?
The process for replacing the fuel filter will vary from one model to another, but overall, it should be within the grasp of the do-it-yourselfer. For some models, specialty tools may be required, so consult a repair manual or a knowledgeable mechanic. Disconnect the battery to avoid any sparking occurring as you work on your fuel lines.
You should be able to access the fuel filter either in the engine compartment or underneath the vehicle near the fuel tank. Before you disconnect the fuel lines that run into and out of the fuel filter, you’ll want to relieve the pressure in the fuel lines. Otherwise you’ll have fuel spraying everywhere, which would be unpleasant and potentially dangerous. You can do this by removing the fuel pump fuse and running the engine until it runs out of fuel and stops.
With that done, you’ll have to disconnect the fuel filter from the fuel lines, dismount it, and attach the new one. While the old fuel filter is off, you may want to inspect the fuel lines. If they are hardened or cracked, they should be replaced. Depending on the application, a special fuel line disconnect tool may be required. Other applications may use threaded fittings that will require a flare nut wrench to remove without damaging the line or rounding the fitting.
