CAMPAIGN: 80 GALLON FUEL TANK RH FILL/VENT CAP DAMAGE

Subject: 80 GALLON FUEL TANK RH FILL/VENT CAP DAMAGE

Models: 1991 Chevrolet P3 With NJ9 ------------------------------------------------------------------------------

TO: ALL AFFECTED DEALERS

General Motors of Canada Limited has determined that a defect which relates to motor vehicle safety exists in certain 1991 Chevrolet P3 Motorhome chassis equipped with a right-hand and left-hand fill 80 gallon fuel tank (NJ9). These vehicles may have been shipped to body builders with damaged fill and/or vent opening caps on the right-hand side. If a left-hand fill system was installed on the tank by the body builder and there was a damaged right-hand cap, the fuel tank system would no longer be sealed. Thus the automatic nozzle shutoff system utilized by gas stations would not work, which would allow gasoline to be forced out of the right-hand opening. If an ignition source were present, a fire could result.

To prevent this condition from occurring, dealers are to inspect for a left-hand fill system and install new caps on the unused right-hand fill and vent openings.
