SDS carries the Merchant Automotive 10491-1 Heavy Duty Injector Return Line Bolt will replace the broken bolt on your vehicle. With the shallow head on the factory fuel injector return line bolt, it is common for the head to strip out during removal or installation. Proper engagement of the Allen wrench in the return line bolt head is critical for accurate torque during reassembly to prevent a fuel leak at the return line fitting. Replace this bolt if damaged to prevent expensive issues or to avoid future potential problems later on down the line.

This Heavy Duty Duramax Fuel Injector Return Line Bolt has been re-engineered to allow nearly twice the amount of tool engagement. The unique head shape found on LB7 return line bolts offers the necessary strength while maintaining proper clearance on other engine parts. 8 Required per engine.
