I suspect I got dirty fuel and my check engine light came on I want to replace the fuel filter but i can't seem to find it.
Where is the fuel filter located? on 2002 Toyota Echo
The fuel filter is part of the fuel pump assembly. It can be accessed by removing the access panel underneath the rear seat cushion, and removing the fuel pump assembly. The check engine light should be scanned to see what code has been set, so that can be diagnosed.
