Merchant Automotive 10491-8 Heavy Duty Injector Return Line Bolt Kit (8-Pack) (2001-2004 6.6L Duramax)

Replace worn or damaged fuel injector return-line bolts on your GM 6.6L Duramax LB7 with the Merchant Automotive Heavy Duty Injector Return Line Bolt Kit (8-Pack) 10491-8. The stock injector return-line bolts are known for a shallow head that often rounds off during removal or installation. This heavy-duty version from Merchant Automotive has been redesigned to allow nearly double the tool engagement with your Allen wrench, ensuring proper torque during reassembly, helping maintain a secure seal at the return-line fitting, and reducing the risk of fuel leaks. The unique head shape offers the needed strength while still maintaining the necessary clearance against surrounding engine components. This kit supplies all eight bolts required for a complete LB7 engine fuel-return line installation.

Features:

• 8-Pack Of Injector Return Line Bolts
• Redesigned Bolt Head For Nearly Double Tool Engagement
• Improved Strength And Torque Retention Versus Stock Bolts
• Complete Set For Full Engine Fuel Return-Line Installation
