Injection line clamps are necessary to prevent injection line breakage. Constant vibration will cause a line to break over time if it is not held still. These injection line clamps perform this function as well as your missing OEM clamp did or if you want added security add as many as you want. This 3 line clamp can be used to bundle three lines together or use it for two lines with wider spacing. Injection line center spacing is 14mm or 9/16" if your lines do not fall exactly on this, no worries, injection lines bend easily and can be safely made to fit. Also available in two and four line clamps.
