Removal & Installation
Before servicing the vehicle, refer to the Precautions section.
CAUTIONHigh pressure lines deliver diesel fuel under extreme pressure from the injection pump to the fuel injectors. This may be as high as 23,200 psi.(1600 bar). Use extreme caution when inspecting for high pressure fuel leaks. Fuel under this amount of pressure can penetrate skin causing personal injury or death. Inspect for high pressure fuel leaks with a sheet of cardboard. Wear safety goggles and adequate protective clothing when servicing fuel system.
