CAMPAIGN:FUEL TANK LINES LOW TORQUE

SUBJECT: FUEL TANK LINES LOW TORQUE

MODELS: 1995 M/L VANS WITH L35 ENGINES

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 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 appointments with owners and to repair their vehicles as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owner is being instructed to contact the GMC Truck Division Consumer Relations Office if the dealer does not remedy the condition within five days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed 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 1995 M/L Vans with L35 Engines. These vans may have fuel lines attached to the fuel tank with less than the specified torque. During the life of the vehicle, as a result of normal vibrations, these fuel lines may loosen to the point of allowing fuel to leak from the lines when the pump is operating. If an ignition source were present, an under-vehicle fire could occur.

To correct this condition, dealers will lower the fuel tank and tighten the fuel tank lines to the proper torque value.

VEHICLES INVOLVED

Involved are CERTAIN M/L Vans built within the following VIN breakpoints:

YEAR Model From Through

1995 M/L SB50766 SB508827

The specific vehicles involved in this campaign have been identified by Vehicle Identification Number (VIN) Computer Listings. These listings are furnished to all involved dealers with the campaign.

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.
