322 STARTING AND OPERATING Bulk Fuel Storage If you store quantities of fuel, good maintenance of the stored fuel is also essential. Fuel contaminated with water will promote the growth of "microbes." These microbes form "slime" that will clog fuel filters and lines. Drain condensation from the supply tank and change the line filter on a regular basis. NOTE: When a diesel engine is allowed to run out of fuel, air is pulled into the fuel system. You may try priming as described below. However, if the engine will not start, refer to the fuel priming procedure in the Service Manual or have the vehicle towed to an authorized Dodge dealer. WARNING! Do not open the high pressure fuel system with the engine running. Engine operation causes high fuel pressure. High pressure fuel spray can cause serious injury or death. Priming if the engine has run out of fuel 1. Add a substantial quantity of fuel to the tank 5 to 10 gallons (19 to 38L). 2. Crank the engine for 1 to 2 seconds. If the engine does not start, then release the key or starter button back to the RUN position (do not turn the key back to the OFF position). The electric fuel transfer pump will continue to run and purge air from the system for about 20 seconds. After 20 seconds, attempt to start the engine again. 3. Start the engine using the Normal Starting Procedure.
