Fuel filter location

Good evening,

The fuel filter is integrated with the Fuel Pump Unit. However, some models continue to incorporate an external fuel filter. If the external fuel filter is not found it should be assumed that the fuel filter can only be replaced by renewing the fuel pump.

The only way to access it is to remove the fuel pump assembly.

Removal

Removing the exhaust system
Detach the exhaust system at the three-way catalytic converter (TWC) and at the rubber mountings.
Hang the exhaust system to one side.

Note! Support the front section of the exhaust pipe so as not to put strain on the exhaust manifold.

There are two filters on that car. One is inside the fuel tank as part of the pump assembly. To replace it you need to drain the tank and remove it. Then once it's out you can remove the retainer ring and remove the pump. The second unit is an inline filter located on the frame rail near the drivers side rear wheel. It has quick disconnect fittings on it.

When you say bad fuel, how is it bad? Something get into the tank like water, oil or diesel or? I ask because unless it's something real bad you could likely just use air pressure to blow the fuel back through the fuel lines, then pump the "bad" fuel out of the tank and replace the external filter if needed. Then add fresh fuel.
