STARTING AND OPERATING 351 Avoid Using Contaminated Fuel Fuel that is contaminated by water or dirt can cause severe damage to the engine fuel system. Proper maintenance of the engine fuel filter and fuel tank is essential. (See Section 7 for Maintenance Procedures). NOTE: Climatized diesel fuel is a blend of Number 2 and Number 1 Diesel fuel which reduces the temperature at which wax crystals form in the fuel. 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). 5
