LML Fuel Filter Vacuum Switch Plug

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.



Note removal of the switch from the harness may result in a CEL depending on the tune the truck has. The switch will need to remain plugged in or pins jumped if the CEL does illuminate.
