Fix Two Common Fuel Filter Sensor Issues on Your 2011-2016 LML Duramax with Our Fuel Pressure Sensor Fooler & Sensor Removal Plug Kit! 

If you own a 2011-2016 LML Duramax, you're likely familiar with the fuel filter restriction sensor, which monitors vacuum between the filter and CP4 pump. Over time, this sensor may fail in two ways:

1. Electrical Failure: The sensor fails electrically, causing a "Change Filter" message and displaying zero percent filter life. This issue prevents filter life from being reset.

2. Sensor Leaks: When the sensor begins leaking, trucks without an aftermarket fuel system may experience a crank/no-start condition. Trucks equipped with a lift pump may develop a fuel leak and hard starting issues.

Our Fuel Pressure Sensor Fooler and  Removal Plug provide a reliable solution for both problems. The Fooler plugs into the factory harness and sends the correct signal to the ECM, ensuring normal fuel pressure (vacuum) is communicated. The Delete Plug allows for complete removal of the sensor. It's o-ringed to guarantee a leak-free installation.

Important: This product is not intended to hide rail pressure issues. If you experience a "Change Filter" message under hard acceleration, your truck may have low rail pressure. Ensure you diagnose and address any underlying issues with rail pressure. However, our fooler and delete plug effectively resolve problems related to faulty or leaking sensors as advertised.
