Condition Involved, Vehicles, Owner, Dealer and Parts Information

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1985-86 Chevrolet Spectrum model vehicles. Vehicles involved in this campaign may experience perforation of the fuel pump diaphragm. A perforated diaphragm can allow fuel to leak from the fuel pump into the underhood area. This condition could ultimately result in an underhood fire without prior warning. Such a fire could, in time, spread to the passenger compartment.
CONDITION INVOLVED

To preclude the possibility of this condition occurring, a fuel pump ventilation hose kit will be installed on all involved vehicles.


VEHICLES INVOLVED

Involved are 1985-86 Chevrolet Spectrum model vehicles produced within the following VIN breakpoints:


MODEL YEAR PLANT FROM THROUGH

1985 Fujisawa F8400105 F8446653

1986 Fujisawa G8400036 G8461910


Involved vehicles have been identified by Vehicle Identification Number computer listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data and are furnished to the involved dealers with the campaign bulletin. Owner name and address data will enable dealers to follow up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of such listing to the follow up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.


OWNER NOTIFICATION

Owners will be notified of this campaign on their vehicles by Chevrolet Motor Division (see copy of owner letter included with this bulletin).
