One problem related to other fuel system has been reported for the 1998 Buick Lesabre. The most recently reported issues are listed below.
Observed a strong gasoline odor after driving the car. The cause of the odor was a leak in the nylon fuel pressure line feeding the rear fuel rail on the engine. The leak in the line was caused by the engine shroud. The engine has a removable plastic shroud, and the edge of the shroud was rubbing on the fuel line and eventually cut through the line and created a pinhole leak.
