# FUEL LINES VISIBLE ON VEHICLE (SERVICE PROCEDURE)

#### SUBJECT: FUEL LINES VISIBLE BELOW VEHICLE

#### MODELS AFFECTED: 1991 DE VILLES AND FLEETWOODS

This bulletin supersedes Service bulletin T-93-3 which should be discarded. This bulletin is being revised to remove the 1992 model year and correct the VIN'S.

Some owners of 1991 DeVilles and Fleetwoods may notice the fuel lines sagging below the underbody floor pan creating an unsightly condition.

Under certain conditions the forces of snow and water splash exerted on the lines may cause them to sag.

Two vehicle populations exist. The service procedure for each is listed below:

#### Service Procedure:

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.
