2 Service Champ Part Service Interval every 30,000 miles / Chevrolet liter Description and Operation The fuel filter element separates particles larger than 10 microns ( in) from fuel moving through it under lift pump pressure. Filter action is very critical to the operation of internal parts of the fuel injection pump. 2

3 FUEL MANAGER/FILTER The fuel manager/filter is an in-line type filter which combines several different functions. It acts as a fuel filter, water separator, water detector, water drain, and a fuel heater. The fuel manager/filter mounts on the rear of the intake manifold. The filter housing has an inlet fitting connecting to the pipe/hose from the lift pump and an outlet fitting connecting to the fuel injection pump with a hose. A third fining connects through a hose to a drain valve mounted on the water crossover/thermostat housing. The fuel manager/filter has a replaceable element. The element has an air vent valve on its top surface that is used during lift pump diagnosis and filter element replacement procedure. The fuel manager/filter also has a water in fuel sensor and a fuel heater. 3

4 Fuel Filter Replacement Procedures Remove engine cover/ intake manifold cover (4 bolts) to reveal the fuel filter location. 2. Fuel Filter housing will be visible (also noted as a fuel manager filter). 3. Remove the vehicles gas cap to depressurize the fuel pressure (if required). 4

5 4. Open the air bleed valve on top of the fuel manager/ filter to release any pressure in the fuel system. 5. Remove the element nut by turning it in a counterclockwise direction. If the nut is unable to turn by hand, use an oil filter wrench to loosen the nut. 6. Remove the filter by lifting, straight up and out of the filter assembly. It is not necessary to drain fuel from the filter assembly to change the filter element since the fuel will remain in the filter assemblies cavity. 5

6 7. Make sure the mating surface between the element assembly and the filter is clean before installation. Install the new filter by aligning the widest key slot located under the element assembly cap with the widest key in the header assembly. 8. Push the element in a downward direction until the mating surfaces make contact. Access can be difficult, due to the filter being at the back of the engine. When re-installing the filter it will be marked front and be indexed to only go on one way. The filter can not be fitted into the canister if it is not aligned properly. 6

7 9. Tighten the element nut securely by hand. 10. Reinstall the engine cover/ intake manifold cover (4 bolts) Tighten to 8ft/lbs. 11. Reinstall the fuel tank gas cap. 12. After the filter is installed turn the ignition key to run and leave it there for 15 seconds, then open the bleeder screw for a few seconds to purge any air. Before starting the engine up rinse any spilled fuel. 13. Cycle the engine (Key on, Key off, Key on, and then start). 14. Start engine and inspect for leaks. Operate the throttle several times to ensure adequate fuel flow. 15. The bleeder screw is made from fragile brass, be careful on the amount of torque applied when tightening or loosening the bleeder screw. 7

8 Service Champ Part Service Interval every 15,000 miles/ Ford liter Description and Operation OPERATION This vehicle utilizes a combination fuel filter/heater/water separator assembly. The assembly traps contaminants to ensure clean fuel is delivered to the injection pump, separate water from the fuel, and warms the fuel to prevent fuel line clogging due to wax formation. This vehicle is equipped with a fuel filter restriction sensor and warning lamp. The indicator is located in the instrument panel to alert the operator of a fuel filter restriction. If the indicator comes on during normal operation, replace the filter. COMPONENTS Fuel Filter/Restriction Sensor The fuel filter is of the spin on type. A sensor in the filter section activates an indicator when fuel flow through the filter is restricted and that the system requires service. Fuel Heater The fuel heater section warms the fuel to prevent wax formation and fuel system clogging when the temperature is below 30 f (-1.8 C). Water Separator The water separator operates on the principal that water is heavier than fuel, and will settle at the bottom of the assembly. There is a water-in-fuel probe located in the water separator section of the assembly. The probe activates a water-in-fuel indicator when approximately 0.1 quart (0.1 liter) of water has accumulated in the bowl. The engine should not be operated while the water-in-fuel indicator is on. The water separator should be drained every 5000 miles or when lamp illuminates. 8
