Injector Return Line Hose Kit, Duramax | 2004.5-2010

Injector Return Line Hose Kit, Duramax | 2004.5-2010

This injector return line hose kit rebuilds the injector fuel return (leak-off) line on one side of the 6.6L Duramax LLY, LBZ and LMM. It replaces GM 97328733 (passenger side) and 98062291. GM's kits are side-specific, but this kit works on either the left or right bank. The factory return line adapters, O-rings and hoses harden and crack with heat, causing fuel seepage on top of the engine and a raw diesel smell.

Key Features

• Replaces GM 97328733 (passenger side) and 98062291
• Fits either the left or right bank
• Return adapters with O-rings
• Adapter retaining clips
• Return line hose, enough for one side; cut to length

Benefits

The return lines come off every time the injectors are pulled, and the old adapters and hoses rarely reseal once they've been disturbed. Because one kit fits either bank, you don't have to work out which side you need, and the hose can be cut to length. Replace if worn or damaged. Commonly replaced at the same time: Injector Fuel Return Line Seal - 8 Pack, Duramax | 2004.5 - 2010, Fuel Injector Return Line Clip Set | 2004.5 - 2010.

Frequently Asked Questions
