# CAMPAIGN:FUEL PIPE REPLACEMENT FUEL LEAK AT THROTTLE BODY

#### Model and Year: 1984 CHEVROLET CITATION AND CELEBRTTY MODELS

#### TO: ALL CHEVROLET DEALERS

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequately repair within 60 days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.

If the condition is not adequately repaired within a reasonable time, the owners may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.

To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owners are being instructed to contact the nearest Chevrolet Zone Office if their dealer does not remedy the condition within five days of the agreed service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.

#### DEFECT INVOLVED

General Motors has determined that a defect which relates to motor vebicle safety exists in certain early production 1984 Chevrolet Citation and Celebrity models equipped with a 2.5L RPO LR8 L4 Engine (VIN Code R). The fuel system in these vehicles may leak at the throttle body injection fuel feed pipe connection. Under certain conditions this could result in an underhood fire. Such a fire could, in time, spread to the passenger compartment and cause burn injuries to occupants remaining in the vehicle.

#### DEALER ACTION

Dealers are to replace the fuel feed pipe on all involved vehicles, per instructions outlined in this campaign bulletin.

Dear Chevrolet Owner:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

General Motors has determined that a defect which relates to motor vehicle safety exists in certain early production 1984 Chevrolet Citation and Celebrity models equipped with 2.5 liter RPO LR8 L4 engine. The fuel system in these vehicles may leak at the Throttle Body Injection fuel feed pipe connection. Under certain conditions this could result in an underhood fire. Such a fire could, in time, spread to the passenger compartment and cause burn injuries to occupants remaining in the vehicle.

To prevent the possibility of this condition occurring, your Chevrolet dealer will replace the fuel feed pipe on your vehicle. This service will be performed at no charge to you.

Instructions for making this correction have been sent to your Chevrolet Dealer. It is estimated that parts will be available to your dealer on April 1, 1985. Please contact your dealer to arrange a service date. The labor time necessary to replace the fuel feed pipe is approximately 20 minutes. Please ask your dealer how much additional time will be needed to process your vehicle.

Your Chevrolet dealer is best equipped to obtain parts and provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date and he does not remedy this condition on the date or within five days, we recommend you contact your nearest Chevrolet zone office, either in person or by telephone. The zone office will assist you and your dealer in getting your vehicle corrected. The locations and telephone numbers of the zone offices are listed in your Owner's manual.

After contacting your dealer and the zone office, if you are still not satisfied that we have done our best to remedy this condition without charge within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street, S.W.. Washington, D.C. 20590, or call 800-424-9393 (Washington, D.C. residents use 426-0123).

We are sorry to cause you this inconvenience, however, we have taken this action in the interest of your safety and continued satisfaction with our products.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
