Polaris RANGER Diesel 2013 Owner's Manual For Maintenance And Safety page 67

Fuel Filter/Water Separator
The fuel filter/water separator is located under the
seat on the right side of the vehicle, between the
engine and fuel tank.
Inspect the separator daily for leaks. Drain water
and replace the separator at the intervals outlined in
the Periodic Maintenance Chart beginning on page
50. Service the separator more frequently if the
vehicle is operated with inferior fuel.
CAUTION! Both fuel and water will drain from the
separator during the following procedure. Use caution
and observe all fuel safety precautions when handling
fuel.
1. Remove the seat. Disconnect the battery.
2. Place an appropriate container under the fuel filter
drain to catch fluids (water and fuel).
3. Slightly loosen the bleed screw to relieve fuel
pressure in the filter. Do not tighten the screw at
this time.
4. Reach under the fuel filter and slightly loosen the
drain valve until the fluids drain from the drain
hole. Do not completely unscrew the drain valve.
5. When fluids stop draining from the valve, tighten
the valve firmly (by hand only).
6. Reconnect the battery.
7. Turn the ignition key on to engage the fuel pump.
Leave the key on only until fuel begins to spit
from the bleed screw, then tighten the screw.
8. Clean up any spilled fuel and soiled shop towels properly.
9. Cycle the key switch from OFF to ON six times, waiting three seconds at each "ON"
cycle to allow the fuel pump to cycle.
10. Start the engine and check for fuel leaks.
11. Reinstall the seat.
