If The Engine Was Started After Incorrect Or Contaminated Fuel Was Used During Refueling

If the fuel system has been contaminated (with gasoline, water, etc.) AND the engine WAS STARTED, the following procedure must be followed:

1. Drain the fuel tank. Use an appropriate fuel container. Refer to DRAINING FUEL TANK - DIESEL  . Dispose of the contaminated fuel using the proper procedures.
   CAUTION:

   Dispose of petroleum based products in a manner consistent with all applicable Local, State, Federal, and Provincial regulations.

2. Remove the fuel tank. Refer to TANK, FUEL, REMOVAL .
3. Ensure the swirl pot indentation below the in the fuel tank electric fuel pump inlet is completely drained of any contaminated fuel.
4. Completely drain the low pressure fuel lines, and install a new fuel filter.
5. Install the fuel tank and fill with clean diesel fuel. Refer to TANK, FUEL, INSTALLATION .
6. Remove the fuel quantity solenoid and inspect filter screen for excessive metallic or sand debris. Refer to SOLENOID, FUEL QUANTITY, REMOVAL . If debris is present skip down to step 10.
7. Disconnect the low pressure fuel return line
8. Connect a clean hose to the low pressure return line fitting and place the other end in a suitable clean container.
9. Turn the ignition ON, and collect the fuel escaping from the low pressure return line into a clean container. Check the fuel sample for metal chips, dirt, or other foreign matter.
10. If any dirt or metal chips are present in the fuel sample, completely clean the high pressure side of the fuel injection system, then install new fuel injectors, the high pressure fuel injection pump, and fuel rails along with new fuel tubes.
11. If gasoline is suspected, do not key on, but first drain high pressure pump.
12. If there are no metal chips or dirt present in the fuel sample, the fuel system is OK. Reconnect the low pressure return line and road test the vehicle to verify normal operation.
