The defect

ON CERTAIN SPORT UTILITY VEHICLES AND PICKUP TRUCKS EQUIPPED WITH 5.3L (RPO L59) V8 ENGINES, THE ENGINE FUEL RAIL CROSSOVER TUBE RETAINER SCREWS WERE NOT MANUFACTURED TO SPECIFICATIONS AND MAY BREAK.

The risk

IF THE TUBE RETAINER SCREW BREAKS, FUEL COULD LEAK FROM THE FUEL RAIL CROSSOVER JOINT, THE ENGINE MAY STALL AND, IF AN IGNITION SOURCE WERE PRESENT, AN ENGINE COMPARTMENT FIRE COULD OCCUR.

The fix

DEALERS WILL INSPECT THE FUEL RAIL CROSSOVER TUBE AND, IF NECESSARY, REPLACE THE RETAINER SCREWS.
