Using the black light, inspect the injectors and fuel lines for signs of leakage. To perform the test, run the engine at 900 rpm. Start engine and allow it to reach operating temperature 140☏ (60☌).Note: It will take a few minutes for the dye in the test bottle to make its way into the high pressure system and up to the injectors.

Remove the rocker cover and install tool (W470589009800) onto the rear of the cam frame to cover the cam gears.Prime the fuel system using the hand primer until there is no air coming out of the return fuel line.This will isolate the engine from the chassis fuel system. Connect the hoses to the fitting on the top of the cap. Install fuel test bottle kit (J-48708) fill one container with ultra-low sulfur diesel fuel and add fuel dye to the fuel in the bottle.Yes, turn the engine OFF, replace the high pressure pump.Are there any leaks coming from the high pressure pump? Inspect the high pressure fuel pump for external leaks.If leaks are still found, replace the PLV connection. Yes, turn the engine OFF, torque the PLV connection, start the engine and recheck.If leaks are still found, replace the Fuel Rail Pressure Sensor. Yes, turn the engine OFF, torque the Fuel Rail Pressure Sensor, start the engine and recheck.Inspect the Fuel Rail Pressure Sensor for leakage.If leaks are still found, replace the lines. Yes, turn the engine OFF, torque the fuel line rail connections, start the engine and recheck.Are leaks found or are there any loose lines? Inspect injector fuel line rail connections for external leaks.Yes, turn the engine OFF, torque the line fittings, start the engine and recheck.Are any leaks found are the line fittings loose? Inspect the high pressure pump to rail feed fittings at the rail and the pump for leakage.Steam clean the entire fuel system prior to inspecting for leaks.To prevent a buildup of potentially volatile vapors, keep the engine area well ventilated during operation.Wear adequate protective clothing (face shield, insulated gloves and apron, etc.).Do not smoke or allow open flames when working on an operating engine.Stop the engine immediately if a fuel leak is detected.Keep those people who are not directly involved in servicing away from the engine.To avoid injury from fire caused by heated diesel-fuel vapors: If there is a suspected leak in the high pressure fuel system, follow these steps to find the leak. High pressure fuel system leaks can cause a variety of problems including difficulty starting, fuel in oil, rough running, low power, and several other issues.
