Three problems related to fuel hoses lines/piping and fittings have been reported for the 1999 GMC Yukon. The most recently reported issues are listed below.
While driving vehicle stalled. The driver tried to restart vehicle but was unable to do so. Driver had the vehicle towed to the dealer, and mechanic determined that the fuel line had to be reattached by a conversion kit.
1999 Yukon fuel leaked out onto the engine. The consumer stated the fuel pump. A recall was issued, however the consumers vehicle was not included in the recall. The anti-lock brakes failed.
Noticed oil spots on garage floor. Drove to GMC dealer for repair. First repair, dealer incorrectly diagnosed problem as fuel filter leak. Second repair, I indicated that the leak was from transfer case not fuel filter. Dealer removed/reinstalled transfer case to replace defective/install a new seal ring to correct problem.
