PRIMARY FUEL FILTERFINAL FUEL FILTER ELEMENT: The filter element collects and holds contaminants and cannot be washed or otherwise restored. To remove the used filter element, proceed as follows:1. Stop the engine and close the diesel fuel line valve (if equipped).2. Unscrew and remove filter.3. Clean the gasket sealing surface on the filter base.
Do not pour fuel into the new filter elements before installing. Prime the system as instructed in the topic, PRIMING THE FUEL SYSTEM.
4. Lubricate the filter gasket with clean diesel fuel.5. Tighten the filter by hand, only tight enough to prevent leaks. (Do not overtighten.)6. Prime the fuel system. Refer to the topic "PRIMING THE FUEL SYSTEM"
REMOVING FUEL FILTER ELEMENT KEEP A NEW FUEL FILTER ON HAND: An extra filter should be kept on hand for replacement. Always keep the filter wrapped in its original carton to insure against dust and dirt accumulation which will shorten the life of the filter or may cause damage to the fuel injection equipment.PRIMING THE FUEL SYSTEM: Any time the fuel flow is broken and air is allowed to get into the fuel system, the system must be primed. If air is left in the lines, the fuel system may become air bound, resulting in inability to start the engine or the misfiring of one or more cylinders.
PRIMING THE FUEL SYSTEMThe fuel priming pump is mounted on the fuel filter housing as shown. If only the fuel filter is changed follow steps 1 through 5. If the fuel system is completely drained or if the engine has run out of fuel continue with steps through 10.1. Check to see that the fuel line valve is open.2. Open the fuel filter vent valve on the fuel filter housing.3. Loosen the knob of the fuel priming pump.4. Operate the pump plunger in and out until the flow of fuel from the vent valve is continuous and free of air bubbles.5. Close vent valve.6. Move governor control to the shut-off position and loosen fuel line nuts (one at a time) at the pump housing.7. Operate priming pump until clear fuel flows from the fuel pump lines. Tighten fuel line nut.8. Repeat for each fuel pump.9. Lock the knob of the fuel priming pump to its original position.10. Start the engine. If the engine does not run smoothly further bleeding may be necessary. With the engine running, open and close the fuel injection line nuts, one at a time, several times in succession to be sure all the air is bled from the system. Tighten fuel line nuts to 30 lbs.ft. (4,1 mkg). Do not overtighten.Fuel Injection Equipment
When improper fuel injection is affecting engine operation, a systematic check should be made to determine the cause. The most likely cause is dirt or water in the fuel. Drain the sediment from the fuel tank. Check the fuel pressure gauge as mentioned in the topic, FUEL FILTERING SYSTEM. Replace the filter element if necessary. Then prime the fuel system until clean fuel reaches the fuel
