Komatsu or Nissan part number is 16310-FT860 for the vaporizer. You will be further ahead buying a new unit and they are available in the aftermarket made by the same supplier as the OEM. With the technology built into trucks now days if you start messing with the fuel system or adding extra components, instead of fixing it correctly, it can create other issues. As I was always taught fix it right the first time otherwise you will spend 5 times the amount down the road.
