Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Water in Fuel
Sometimes, water can be found in the fuel tank along with diesel fuel. This can happen if the service station does not regularly inspect and clean their fuel storage tanks, or the fuel is contaminated as received from the service stations suppliers.
If water is detected by the Water in Fuel Sensor, a Water-In-Fuel light will illuminate. If the Water-In-Fuel light illuminates, the water must be drained from the fuel system on the vehicle.
