CONSEQUENCE SUMMARY
Fuel leakage, in the presence of an ignition source, could result in a fire.
CORRECTIVE SUMMARY
Dealers will inspect and, if necessary, replace the engine fuel rail with a new stainless steel fuel rail. Dealers will also install a revised chassis fuel return line. The recall began on June 2, 2004, for 1996-1997 Oldsmobile Aurora vehicles.
