Our solution to replacing the factory metal return lines on 6.2 and 6.5L diesel engines.  This kit is designed to replace both metal lines on the engine; the one across the front and the one under the intake manifold.


  • Billet aluminum fuel distribution block with threaded ports and hose fittings
  • 1/4" hose to connect injection pump return
  • 5/16" hose to connect to the factory return line at the rear of the engine, going to the fuel tank
  • Clamps for the 1/4" and 5/16" hose
  • Injector return hose to connect both banks of fuel injectors. This is push lock style hose that doesn't need clamps
  • 2 end caps with spring clamps to cap one end of each injector bank

Upgrades Available!

  • You can now choose an upgrade to clear fuel return hose
    • This allows you to visually monitor fuel return flow and check for air in fuel issues
