What Is A Fuel Filter And Why Is It Important?

Fuel filter

A fuel filter is a small part that looks like a soda can. It has pleated filter material inside, and its purpose is to clean the fuel before it goes into the engine. Your Toyota’s engine needs clean fuel because dirty fuel causes a bunch of problems, such as:

  • Decreased power
  • Stalling or misfiring
  • Premature failure of fuel injectors

This post has a more thorough explanation of fuel filters and how they work.

How Do I Know If My Fuel Filter Is Failing?

On older cars, fuel filters last about 30K miles. On newer cars, fuel filters last the lifetime of the engine. Fuel filters can still fail, though. If you've got an older Toyota, it’s important to check your fuel filter as soon as you suspect that something’s wrong with it. You can either:

  • Perform a fuel pressure test
  • Visually inspect the fuel filter

This tutorial walks you through both processes.

Should I Buy An OEM Or An Aftermarket Fuel Filter?

If you’ve confirmed that your fuel filter is due for a change, it’s time to choose a replacement part. You may be wondering if you should get an aftermarket fuel filter instead of an OEM filter. It’s actually not a wise choice, and this guide explains why. In a nutshell:

  • OEM fuel filters last longer
  • Some aftermarket fuel filters tend to fail early
  • OEM fuel filters are built with quality materials
  • Most aftermarket fuel filters aren’t built with quality materials
  • OEM fuel filters are an exact replacement, which makes them easy to install
  • Aftermarket fuel filters don’t always fit right; many of them are prone to leaks
  • OEM fuel filters come with a warranty
  • Most aftermarket fuel filters don’t have a warranty
