The DTech RTF26410 Injector Return Line Kit for your 2004.5-2010 GM 6.6L Duramax can be used in place of the GM Fuel Return Line kits 97328733 and 98062291. While the GM kits are specific to right or left side, the DTech RTF26410 kit can be used with the injectors on either side of your engine. This makes the DTech Kit an extremely affordable alternative to the expensive return lines you would get at the dealer. 

The RTF26410 includes the return adapters and o-rings, adapter retaining clips, and a length of return line hose sufficient for either engine side. 


  • One Kit Per Bank (2 Required For Both Sides)
  • Affordable Quality Alternative To Expensive GM Parts
