So the lights came on for my fuel filter and water in in fuel. i changed my fuel filter and i put the two bottles of water remover in the fuel and the codes didnt go away. the code for the water in fuel comes on every other start and the fuel filter light is always on. I also ran the codes on a OBD and nothing came up but the lights are on. what should i do to get them to go away?

 

Did you drain the fuel bowl?

 

Get the water out of the fuel tank, get some fresh diesel in there and have a few filters on hand.
