CAMPAIGN: FUEL FILTER LEAKAGE POLICE & TAXI MODELS

Models: 1990 Chevrolet Caprice Police (SEO 9Cl) and Taxi (SEO 9C6) Models

TO: ALL GENERAL MOTORS DEALERS

General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in certain 1990 Chevrolet Caprice police and taxi model vehicles. These vehicles have plastic fuel filter assemblies which may develop leaks. Such a leak could result in a vehicle fire due to static charge buildups found in the plastic fuel lines and fuel filter which may act as an ignition source.

To prevent this condition from occurring, a metal fuel filter and filter bracket will be installed on all involved vehicles.
