Owner Letter
Dear GMC Owner:
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.
General Motors has determined that a defect which relates to motor vehicle safety exists in certain 1990 GMC M-Vans with 4.3L or 2.5L engine. These
vehicles may have fuel return hoses which may break at either crimped coupling. If this coupling was to separate and an ignition source was present, an
engine compartment fire could occur.
To prevent this condition from occurring, a properly crimped fuel return hose will be installed on all involved vehicles. This service will be completed
for you at no charge.
Instructions for performing this service have been sent to your GMC dealer. Parts are available. Please contact your dealer to arrange a service date. The
labor time necessary to perform this correction will be approximately 30 minutes. Please ask your dealer how much additional time will be needed to
schedule and process your vehicle.
