The 2011-2016 LML trucks were equipped with a vacuum switch to notify the drive when the fuel filter has become dirty or clogged. When a aftermarket lift pump is installed this switch can leak fuel due to a torn diaphragm.
This plug will remove the switch from the fuel system to stop or prevent the leak.
Install is quick and easy.
