CAMPAIGN: DIESEL ENGINE FUEL LINES CLIPPING
Model and Year: 1990 CHEVROLET C/K 15-35 SERIES TRUCK WITH 6.2L DIESEL ENGINES (RPO'S LH6 & LL4)
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 repair within sixty (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 owner 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 that is being sent to owners, the owners are being instructed to contact the Chevrolet Customer Assistance Center if their dealer does not remedy the condition within five (5) days of the mutually agreed upon 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 vehicle safety exists in certain 1990 Chevrolet C/K 15-35 Series Trucks with 6.2L diesel engines. The front diesel fuel feed and/or return lines of these vehicles can contact the automatic transmission shift linkage cordon shaft and/or, on K models, the front propshaft. If this contact occurs, a hole could be rubbed through the fuel line and a diesel fuel leak may occur near the exhaust crossover pipe. A fuel leak of this type may result in an engine compartment fire.
To prevent this condition from occurring, Chevrolet dealers will install a new design fuel line routing bracket. Additionally, fuel lines will be inspected for wear and, if necessary, replaced.
VEHICLES INVOLVED
Involved are certain 1990 Chevrolet C/K 15-35 Series Trucks with 6.2L diesel engines built within the following VIN breakpoints:

Involved vehicles have been identified by Vehicle Identification Number Computer Listings.

Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.

The fuel feed and/or return lines of these vehicles can contact the automatic transmission shift linkage cordon shaft and/or, on K models, the front propshaft. If this contact occurs, a hole could be rubbed through the fuel line and a diesel fuel leak may occur near the exhaust crossover pipe.

WHAT WE WILL DO
To prevent this condition from occurring, your Chevrolet dealer will install a new design fuel line routing bracket. Additionally, fuel lines will be inspected for chaffing and, if necessary, replaced. This service will be performed for you at no charge.

Please contact your Chevrolet dealer as soon as possible to arrange a service date. Instructions for making this correction have been sent to your dealer. Parts are available. The labor time necessary to perform this service inspection/correction is approximately 30 minutes to 1 hour. Please ask your dealer if you wish to know how much additional time will be needed to schedule and process your vehicle.
Your Chevrolet dealer is best equipped to obtain parts and provide service to insure that your vehicle is corrected as promptly as possible. If, however, you take your vehicle to your dealer on the agreed service date, and they do not remedy this condition on that date or within five (5) days, we recommend you contact the Chevrolet Customer Assistance Center by calling 1-800-222-1020.
After contacting your dealer and the Customer Assistance Center, if you are still not satisfied that we have done our best to remedy this condition without charge and 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 1-800-424-9393 (Washington D.C. residents use 366-0123).

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.
