With the shallow head on the stock bolt, it is common for the head to round out during removal. The MA Heavy Duty LB7 Injector Return Line Bolt has been redesigned to allow nearly double the tool engagement. Proper engagement of the Allen wrench is crucial for accurate torque during reassembly to avoid a fuel leak at the return line fitting. The unique head shape offers the needed strength while maintaining proper clearance on other engine components
