That hose cushion is in my opinion intended to be at the coolant hose that goes to the block between the oil filter housing and the injection pump. It provides protection from chaffing on the oil filter housing. I found mine somewhere in the bowels of the engine bay ars well...The plastic clip is as stated from the linkage at the rear of the vac. control valve. I just re-installed my vac. control valve last night so your picture is very familiar.
