The procedure for "Draining the Fuel Tank" in this bulletin is to be used in place of the procedure printed in the 1988 Regal Service Manual. Fuel must be drained through the filler vent tube at the fuel tank. Do not attempt to drain fuel through the filler neck, as damage to the filler neck check ball will occur.
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.
