View DetailsThe DTech DT660023 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 DT660023 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 DT660023 includes the return adapters and o-rings, adapter retaining clips, and a length of return line hose sufficient for either engine side.
Features:
- One Kit Per Bank (2 Required For Both Sides)
- Affordable Quality Alternative To Expensive GM Parts

Genuine Bosch OEM Fuel Return Line, 2004.5-2010 GM 6.6L LLY/LBZ/LMM (RH)

Description
Fitment: Passenger Side(RH)
We recommend replacing these hoses at the time of injector replacement to minimize debris/contamination reaching the new injectors.
These lines can be cracked/rotted/weathered which can cause many issues down the road.

Fuel return line lbz
The girls looked at each other, and I went out. Taking the hose, I opened the tap on the hose and lowered a little water into the basin to clear the air from the hose. And then smeared the long tip with Vaseline. Meanwhile, my charges came in after me. They stood side by side, watching my manipulations.
