2007.5-2010 Duramax LMM Merchant Automotive Fuel Injector Line Set - ALL 8

Complete set of high pressure Duramax fuel lines by Merchant Automotive. These lines connect from the fuel rail to the fuel injector. Built to meet or exceed OE specifications for proper fit and performance.  

We recommend new lines when replacing the fuel injectors if there are signs of corrosion or rust on the old ones. This will prevent debris from being introduced into the injectors.
