Fuel Filter


On all models except the Millenia, the fuel filter is attached to a bracket located in the left rear of the engine compartment, next to or beneath the brake master cylinder fluid reservoir.

On the Millenia, the fuel filter is located beneath an access cover in the trunk. Access to the cover is achieved by removing the trunk mat to expose the cover.

The fuel filter should be serviced according to the Maintenance Intervals Chart at the end of this Section.


Do not allow fuel spray or fuel vapors to come in contact with a spark or open flame. Keep a dry chemical fire extinguisher nearby. Never store fuel in an open container due to risk of fire or explosion.
