SPECIAL POLICY: LACK OF SPECIFIED 20 GAL. FUEL TANK. GMC Truck S15 Pickup - 2WD 1988

For 1990-2009 cars

# SPECIAL POLICY: LACK OF SPECIFIED 20 GAL. FUEL TANK

#### MODELS: EARLY 1988 S-15 PICKUP TRUCKS (EXCEPT X81 AND X9H)

General Motors has determined that instead of the specified 20 gallon fuel tank, a 13 gallon fuel tank was installed in certain 1988 S-15 pickup and chassis cab model trucks (except options X81 and X9H) built at the Moraine and Shreveport assembly plants. The price label on an affected vehicle states that the unit has a 20 gallon tank (the price of the 20 gallon tank is included in the base vehicle price) but the absence of NK2 from this service information label indicates that it has a 13 gallon fuel tank. Dealers were notified of this matter on November 10, 1987.

#### SPECIAL POLICY ADJUSTMENT

Original owners of record who purchased their vehicles on or before November 10, 1987, will be contacted and offered a choice of the following:

A. $100.00 total reimbursement adjustment incentive.

OR

B. Installation of a 20 gallon fuel tank at no charge.

When the original purchaser requests reimbursement, that customer MUST sign and date the Option Selection form included as part of the owner letter (extra copies to be reproduced locally, if needed). The signed form and a copy of the check issued to the owner is to be attached to the dealer's file copy of the request within thirty (30) days after dealer credit is received, and retained for twenty-four (24) months from date of credit.

For vehicles in dealer inventory after November 10, 1987, and not sold, dealers were requested to disclose this condition to the prospective purchaser and to make an appro- priate price adjustment in the amount of $51 MSRP from the MSRP for the base vehicle.

This is GMC Truck's calculation of the portion of the vehicle's MSRP attributable to the larger fuel tank ($44.01) dealer price.

For vehicles still in dealer inventory and not sold in January, 1988, new price labels reflecting the above were sent to dealers with the request that they be applied to the affected vehicles. Dealers should take the necessary steps to disclose to customers the size of the fuel tank installed in an affected vehicle prior to sale.

The Special Policy Adjustment will remain in effect until May 15, 1989 with no mileage restriction.

This Special Policy Adjustment Bulletin should be filed in the three-ring binder fumished to the dealer by General Motors.

#### SERVICE PROCEDURE

#### NOTICE: Intank electric fuel pump will be reused; do not discard intank fuel pump.

1. Drain fuel tank. Disconnect the negative battery cable. Have a dry chemical (Class B) fire extinguisher nearby.

#### CAUTION:

To help avoid a fire or explosion, never drain or store gasoline or diesel fuel in an open container.

Use a hand operated pump device to drain as much fuel as possible through the filler neck. On some fuel tank installations, the filler neck is too long to gain access to the fuel. If the tank is not full, disconnect filler neck hose, at the fuel tank, to gain access to the fuel.

a. Disconnect fuel feed pipe and attach a hand operated pump device. b. Energize the fuel pump relay. c. With fuel pump running, operate hand pump to remove fuel.

2. Relieve fuel system pressure (2.5L Engine only).

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.
