Fuel Return Line: Service and Repair
CAUTION: The water/diesel fuel mixture is flammable. The water/diesel fuel mixture could be hot. In order to help avoid personal injury and
property damage, do not touch the fuel coming from the drain hose. Also do not expose the fuel to open flames or sparks.
Be sure you do not overfill the container. Heat (such as from the engine) can cause the fuel to expand. If the container is too full, fuel could be
forced out of the container. This could lead to the risk of personal injury and vehicle damage.
