V6 Fuel Injector Leak off Hose OM642

This hose attaches to the top of each injector and returns the unused fuel back into the fuel system. It can get damaged over time or when it is removed due to injector work. It fits the V6 engine only. 
We also highly recommend replacing the tiny o-rings that seal each end of this hose fitting to the injector. They also can get worn out over time or damaged by the removing and reinstalling of this hose and begin to leak diesel fuel down the side of your engine and onto the ground.
