A Gasket Too Far

Certain 2017 model year Buick LaCrosse vehicles may have been built with an unnecessary gasket in the high pressure fuel pump assembly. The fuel pump may wear out early and this could lead to degradation of engine performance over time.

There is no extra gasket required when replacing the fuel pump. Be sure to remove the old gasket before installing the new fuel pump. Remove the gasket that comes with the new pump before installation.
