Ford

Changed out both filters in 6.0 diesel and sensor is still on. do i need to drop the fuel tank and is there another filter in the tank?

Mounted on the frame under the driver side door is an allen head screwed into the sensor. unscrew the allen head and drain for a few seconds. if light is still on may need to replace sensor. i replaced a lot of these at the dealer. make sure your vehicle is not still under warranty for this. 100k power train warranty will still cover this..
