Draining Water from the Fuel Filter
CAUTION
• Clean off any fuel that has adhered to the vehicle body.
• Starting the engine immediately after draining the water from the fuel filter
requires a little more time than usual. If the engine doesn't start in 10 seconds,
wait for a while and try again.
• Fuel will be mixed in the drained water. Dispose of it in a method conforming to
the regulatory requirements in your country.
SERVICE AND MAINTENANCE
Vehicle-side Pre-fuel Filter
1. Loosen the drain plug on the clear
element case at the bottom of the fuel
filter to drain out water.
2. Tighten the drain plug once all of
the water has drained off. If the
amount of water exceeds 0.3 liters
(0.08 US gal./0.07 Imp gal.), drain the
water from the engine-side main fuel
filter as well.
3. Check that there are no fuel leaks
from the drain plug and that the water
separator (fuel filter) warning light
stays off after the engine is started.
4. Bleed the fuel system if the large
quantities of water and diesel fuel are
drained out from the fuel filter.
