Hanson Subaru Common Service Questions: When Should I Replace the Fuel Filter on my Subaru

Get answers for your fuel filter questions

Fuel filtration technology has come a long way in the past few decades. Fuel filters are more effective and last longer than ever before. However, this does come with one drawback: Now that they last five to six years on a typical car, manufacturers are putting the fuel filter in the fuel tank itself - making it virtually impossible for the average weekend mechanic to replace. Instead, you'll need to bring your vehicle to a Subaru dealership for this service.

The expert technicians at your local Subaru service center will hoist the car up, remove the fuel tank safely and install a new filter. We'll also assess the condition of the fuel pump, which is also now stored in the fuel tank. If it's on its last legs, it can be conveniently replaced now, instead of having to pull the fuel tank off again just a few weeks or months down the road.

Consult your owner's manual for the recommended fuel filter replacement interval. For example, the 2013 Subaru Outback should have its fuel filter replaced every 5 years or 60,000 miles, whichever comes first. If you haven't had the fuel filter replaced and your vehicle has exceeded this mileage, now is a great time to get a new fuel filter! If the fuel filter gets completely clogged or develops a hole, that can cause big problems with expensive repair bills.

What Happens When my Fuel Filter Fails?

Before it arrives at the gas station, gasoline is incredibly pure. However, it picks up debris as it's hauled around the globe by ship and by truck until it finally ends up in the underground tanks at your local gas station. When you finally do pump your gas, debris picked up during transportation and storage makes its way into your fuel tank. The fuel filter protects your fragile fuel injectors from this debris.

If particulate makes its way past the fuel filter, it can clog up the fuel injectors, sapping your engine's power and even causing it to stop altogether. If your fuel filter is old enough, it can develop holes for debris to pass through.

What's more, a clogged filter might simply not let enough fuel into the engine. As it picks up dirt and dust, the fuel filter becomes clogged, and less fuel can pass through. Eventually, the ideal amount of fuel won't make it to the engine, causing it to run lean. This can also result in a dramatic loss of engine power, and can even cause the engine to hesitate and misfire.
