615 616 617 Diesel Engine Fuel Injector Hard Line Clamp - USED

In working on many 61x series diesel engines, I have often found one or more of these clamps missing. Missing or loose clamps are the number one reason for injector hardline crack failure. There should be a clamp like this between every two hard lines to minimize vibration fatigue failure. ONE (1) USED clamp is included with the correct bolt and nut.
