Injector(S), Fuel: Description: Description
High-pressure fuel lines deliver fuel under extreme pressure from the injection pump to the injectors. This may be as high as 1800 bar (26, 106 psi). 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 high-pressure fuel leaks with a sheet of cardboard. Wear safety goggles and adequate protective clothing when servicing the fuel system.
Three electronically controlled fuel injectors are located on top of each cylinder bank. The injectors generate a fine fuel atomization at injection pressures of up to 1, 800 bar (26, 106 psi). Each injector is held in place by a tensioning claw and retaining bolt. A copper seal ring is located on the injector tip to seal off the injector to the combustion chamber. When servicing the injectors, always replace the copper seal ring and inspect the seal in the cylinder head cover. Lubricate the body of the injector with Mopar® 05012249AA - Nickel Antisieze Compound, or Molikote Anti-Fretting Paste (MB part number A001-989-42-51-10).
