Where is the fuel filter located on an 89 300E? My son has been searching all morning and can't find the bloody thing.

 

It´s under the car. Beneath the rear seat, on the passenger side. You need to remove a small plastic cover retained by four plastic nuts to gain access to it. Required tools are a 19mm and a 17mm wrench. Plus a screwdriver..

Cheers..

 

Thank you!! Think he looked there, but will send him there again.

 

If it's like my car, it's in front of the differential. The plastic cover that needs to be removed is flush with the undercarriage. I remember using a socket ratchet with a long (12"?) extension to remove the cover fasteners, which were angled.

Make sure he works safely.

 

Before you send your son down under (the car) remember it is a awefully messy job. Fuel is draining all over even if you clamp all the fuel lines. If you dont have a lift, I would not DIY. The lines and connectors mostly are corroded and you may need replacement parts.
