Power Loss and Priming issues are present in some trucks because of a leak in the stock Water In Fuel sensors. Fix this issue by using our Water In Fuel Drain as a direct replacement. Our Drains delete the factory Water sensor mechanism so that your filter is less prone to leaks. This replacement will not turn your check engine lights on or throw any trouble codes. Draining the Filter with the new Drain: Water is heavier than fuel and will settle to the bottom of the filter and appear to be a different color. In high humidity areas drain frequently. Make sure engine is off and cool to the touch Open vent plug Open drain valve to remove water, close drain immediately after water has emptied from filter. *If drain valve is left open, entire fuel tank may drain NOTE: You will need to secure the stock water in fuel sensor plug off to the side if you have a water in fuel sensor on your truck.
