Description
Duramax Injector Return Lines, Metal Fittings | 2004.5-2010
The Merchant Automotive Fuel Injector Return Line and Clip Set with Metal Fittings replaces both the left and right bank injector return lines on 2004.5-2010 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks with the LLY, LBZ and LMM 6.6L Duramax diesel. The return lines carry leak-off fuel from each injector back to the fuel return system. Factory lines often harden, crack or leak at the fittings with age and heat. This set uses metal injector fittings in place of the original plastic and includes all 8 retainer clips, so you can replace the entire return circuit in one job.
Note: The return line hose must be cut to length and assembled to the fittings before installation.
