Removing water from the fuel in your truck is important to maintaining engine health–water in the fuel can severely damage components of your injection system. Water in your fuel tank can also provide an environment for fungi and bacteria to grow, which can corrode fuel lines and rubber components. If the water in the fuel light comes on, you should change your fuel filter immediately. We recommend emptying the water from your fuel system about every 5,000 miles. The procedure is detailed below.
- Park the car and turn off the engine.
- Find the fuel filters underneath the car and locate the yellow tab.
- Place a container under the valve.
- Twist the valve until water drains.
- Once it’s done draining, retighten the yellow valve and properly dispose of the fuel-contaminated water.
