Refer to Procedure 005-016. See detail. General Information TOC There are four different mounting locations available for high-pressure
fuel pumps. The pump can be mounted in a high or low position in either a front or rear gear train engine. Due to the number of different fuel pump mounting locations, the steps in this procedure have been written to be generic. Some of the illustrations do not represent the parts being removed or installed. CAUTION Use caution when disconnecting or removing fuel lines, replacing filters and priming the fuel system, so that fuel is not spilled or drained into the bilge area. Do not drop or throw filter elements into the bilge area. The fuel and fuel filters must be discarded in accordance with local environmental regulations.
CAUTION Be sure that the fuel inlet and return valves are returned to the open position before cranking the engine. Engine damage can result if the valves are in the wrong position when the engine is cranked or started. Environmental damage can also occur. Refer to Procedure 005-999 in Familiarization section for further information. Test TOC CAUTION Clean all fittings before
disassembly. Dirt or contaminants can damage the fuel system. With the keyswitch ON and the engine cranking, check the high pressure injection pump. Check the high pressure injection pump fuel flow as follows: Disconnect the high pressure fuel line to the fuel rail from the high pressure injection pump. Connect a clear hose to the outlet of the high pressure injection pump. Run the high pressure fuel line into an empty bucket. Crank the engine for 30 seconds and measure the fuel pump flow. Minimum fuel pump flow is 75 ml
[2.5 oz] in 30 seconds at 125 rpm or 90 ml [3.04 oz] in 30 seconds at 150 rpm for 4-cylinder and 6- cylinder engines. If the minimum fuel flow is achieved, the electronic fuel control (EFC) actuator is defective. Refer to Procedure 005-007 in the ISB e, ISB and QSB (Common Rail Fuel System) Series Engines Service Manual, Bulletin 4021271. If the minimum fuel flow is not achieved, the highpressure injection pump is defective and needs to be replaced. Summary 1
If the engine can be started, a measurement of the fuel return flow can diagnose a highpressure fuel pump problem. The following steps describe how to test the high-pressure fuel pump return flow. WARNING The fuel pump highpressure fuel lines and fuel rail contain very high-pressure fuel. Never loosen any fittings while the engine is running. Personal injury and property damage can result. A malfunctioning fuel return overflow valve or fuel pump can result in high return from the fuel pump. The return fuel flow from the pump must be measured at idle conditions. The fuel system leakage test in the INSITE electronic service tool can be used to increase system pressure and therefore increase the ability to detect high leakage. Summary 2
Without Electric Lift Pump Disconnect the fuel pump return line. 3.9L and 5.9L Engines Attach the fuel pressure gauge adapter, Part Number 3164044, to the fuel pump return fitting. Install a quickdisconnect blockoff fitting, Part Number 3164583, on the disconnected drain line. 4.5L and 6.7L Engines Attach the female quick-disconnect fuel drain hose, Part Number 4918434, onto the fuel pump drain connection. Install a quick-disconnect block-off fitting, Part Number 4918464, on the disconnected drain line. Summary 3 Summary 4 Summary 5 With Electric Lift Pump Follow the fuel return line from the fuel pump to the fuel return manifold. At the fuel return
manifold, remove the banjo bolt for fuel pump return line and install test fitting, Part Number 3164618. CAUTION If tool Part Number 3164618 is installed at the fuel pump, it will block return flow and cause possible damage to the fuel pump. Install tool Part Number 3164618 only at the fuel return manifold. For automotive and industrial applications, the return manifold is located near the top of the engine, beside the fuel rail. Summary 6 For marine engines, the return manifold is located on the side of the engine block, next to the ECM.
Summary 7 WARNING Fuel can be returned at highly elevated temperatures. Wear safety glasses and protective gloves and clothing when performing this test. Avoid contact with returned fuel. Place the end of the fuel pressure gauge adapter tool or fuel drain hose into a 500 ml graduated beaker, Part Number 3823705. Start the engine.
Measure the flow rate by recording the amount of time necessary to fill a 400 ml graduated beaker. Flow Specification: Standard Idle Conditions (750 rpm) 4- and 6- cylinder 400 ml (maximum) in 25 seconds Summary 8 Maximum Flow: Standard Idle Conditions (750 rpm) 4- and 6- cylinder 400 ml in 25 seconds Preparatory Steps TOC WARNING Batteries can emit explosive gases.

arcing, remove the negative (-) battery cable first and attach the negative (-) battery cable last. Summary 9 Disconnect the batteries. WARNING Fuel is flammable. Keep all cigarettes, flames, pilot lights, arcing equipment, and switches out of the work area and areas sharing ventilation to reduce the possibility of severe personal injury or death when working on the fuel system. CAUTION Do not vent the fuel system on a hot engine; this can cause fuel to spill onto a
hot exhaust manifold, which can cause a fire. Summary 10 CAUTION Drain the fuelwater separator into a container, and dispose of the contents in accordance with local environmental regulations. CAUTION Clean all fittings before disassembly. Dirt or contaminants can damage the fuel system. Disconnect and remove the lowpressure fuel supply and drain lines.

Prime TOC Automotive and Industrial WARNING
The fuel pump highpressure fuel lines and fuel rail contain very high-pressure fuel. Never loosen any fittings while the engine is running. Personal injury and property damage can result. CAUTION Be sure that the fuel inlet and return valves are returned to the open position before cranking the engine. Engine damage can result if the valves are in the wrong position when the engine is cranked or started. Environmental damage can also occur.

Refer to Procedure 005-999 in Familiarization section for further information. With Electric Lift Pump Allow the lift pump to run by turning the key switch ON and waiting 30 seconds before starting. NOTE: It is not necessary to vent air from the highpressure fuel system before starting the engine. Cranking the engine will prime the fuel system. Operate the engine and check for leaks. Summary 57 Summary 58 With Hand Priming Pump Dry Fuel Filter and Fuel Tubes: this condition occurs if the engine has come from the manufacturing plant without being tested before shipping, if the fuel
filters have been changed. Before starting the engine, pump the hand priming pump 120 times. Full Fuel Filter and Fuel Tubes: This condition occurs if the engine is being installed for the first time after being built, but was tested at the manufacturing plant or is being reinstalled. Before starting the engine, pump the hand priming pump 40 times. NOTE: NOTE: It is not necessary to vent air from the highpressure fuel system before starting the engine.

Fuel is flammable. Keep all cigarettes, flames, pilot lights, arcing equipment, and switches out of the work area and areas sharing ventilation to reduce the possibility of severe personal injury or death when working on the fuel system. CAUTION Use caution when disconnecting or removing fuel lines, replacing filters and priming the fuel system, so that fuel is not spilled or drained into the bilge area. Do not drop or throw filter elements into the bilge area. The fuel and fuel filters must be discarded in accordance with local environmental regulations. CAUTION Failure to properly prime the fuel system on marine
engines can result in damage to the fuel cooler. Be sure the drain valve(s) are open. Be sure a good flow of fuel is present through the fuel cooler by cycling the keyswitch at least five times before starting the engine. Summary 62 NOTE: It is not necessary to vent air from the highpressure fuel system before starting the engine. Cranking the engine will prime the engine. The fuel transfer pump is initiated by turning the keyswitch to the ON position. The pump will run for 50 to 60 seconds, then shut off. Priming the fuel system requires cycling the keyswitch several (5 or more) times to make sure the fuel filter is primed properly and that all the air is out of the fuel system, down stream through the fuel cooler.
