The Cornwell Ford 6.7L Diesel Injection Socket Set, No. SLC11400, is a 17mm, 12 point flare nut socket with deep crowsfoot that gives technicians the ability to remove various injector lines, the company says. The geometry of these tools is designed for removing injectors without breaking or damaging the electrical connections. The crowsfoot can be spun by hand under the bent lines. The long socket has the clearance required and linear shape to properly torque the fuel lines.
