Removal Procedure

WARNING:

High Pressure Lines deliver diesel fuel under extreme pressure from the injection pump to the fuel injectors. This may be as high as 1600 Bar (23200 psi). Use extreme caution when inspecting for high pressure leaks. Fuel under this amount of pressure can penetrate skin causing personal injury, or death. Wear safety goggles and adequate clothing when servicing this fuel system.

  1. Turn OFF the engine for 30 seconds before proceeding. This will ensure fuel pressure has purged from the fuel system.

    NOTE:
