The fuel filter for this vehicle is located in the fuel tank and is part of the pump. It does not require replacement unless you need to remove the pump for another reason or have fuel contamination.

I attached the process on how to adjust the idle but what is the idle currently? If it is around 700 or with 50 RPM either way then it is within range. Even if this is outside the range but the vehicle is running well, I would not adjust it. If the idle gets too low and is running rough then you should adjust it. Otherwise, I would not mess with it.
