Fuel/Water Separator

Water separator should be drained every 5000 miles or when warning light glows. Diesel fuel can damage asphalt and painted surfaces. Always place a drain pan under conditioner to collect fuel. To drain conditioner, use the following procedure:

1. Stop vehicle and turn engine off. Open drain valve located under fuel filter water separator. Allow fuel to drain for about 15 seconds or until water is completely drained. Tighten and ensure drain valve is fully closed or seated.
2. Restart engine and check warning light. If warning light continues to glow, fuel system needs to be checked or repaired. The only serviceable item on the separator is the water level sensor.
