The Bosch 0445218025 is the genuine left-bank (driver side) common-rail fuel rail for the 5.0L Cummins V8 in the 2016-2019 Nissan Titan XD. It stores high-pressure fuel from the injection pump and feeds the four injectors on the left cylinder bank, so a cracked, leaking or contaminated rail shows up as hard starts, low rail pressure codes, rough running and lost power.

Bosch supplied the original common-rail system for this engine, and this rail matches the factory Nissan 17520-EZ40B assembly. It is a new part, not a remanufactured unit, and installs with no modifications.

Vehicle Fitment & Technical Installation Notes

Common-rail systems are very sensitive to dirt. Clean the area around the rail before removal, cap every open fuel port and line right away, and keep the new rail's caps in place until each line is connected. Torque the high-pressure fittings and mounting bolts to the factory service manual values, then prime the fuel system and check for leaks before driving.
