416 SERVICING AND MAINTENANCE
Upon proper draining of the water from both
fuel filters, the “Water In Fuel Indicator Light”
will remain illuminated for approximately
10 seconds. If the water was drained while the
engine was running, the “Water In Fuel Indicator
Light” may remain on for approximately three
minutes.
NOTE:
Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the environ-
ment. Contact an authorized dealer, service
station, or government agency for advice on recy-
cling programs and for where used fluids and
filters can be properly disposed of in your area.
Drain the fuel/water separator filters when the
“Water In Fuel Indicator Light” is ON. Within
10 minutes of vehicle shutdown, turn the engine
mounted filter drain valve (located on the side of
the filter assembly) counterclockwise 1/4 turn,
and turn the under body mounted filter drain
valve (located on the bottom of the filter
assembly) counterclockwise 1 full turn. Then turn
the ignition switch to the ON position, and allow
any accumulated water to drain. Leave the drain
valve open until all water and contaminants have
been removed. When clean fuel is visible, close
the drain valve following these guidelines:
1. Rotate the drain clockwise to close until
you feel resistance from the internal seal.
2. Continue turning the drain 1/2 of a turn to
properly compress the seal.
NOTE:
Over-compression of the seal due to over-tight-
ening of the drain will damage the seal, cause a
leak, and require the entire sensor to be
replaced.
3. Turn the ignition switch to OFF.
The sensor drain should not be over-tightened
during normal service operations to avoid
internal damage and future fuel leaks. The
drain should be closed and secured without the
use of tools.
If more than a couple ounces/milliliters of fuel
have been drained, follow the directions for
“Priming If The Engine Has Run Out Of Fuel.”
