Description Reviews This USED MINI Cooper Vacuum Pump Fitting is a part that you can not buy new. The only way is to buy it on a new pump. This is a USED part off of bad pumps or bad motors. We cleaned them up and test to make sure the check valve works. We have never seen this part fail unless you break it off in the engine bay! A small price to pay to save a lot! We only have a small supply so we have set the inventory on these and we update it as we get more. Only Fits: N16 Motor N18 Motor N18 JCW Motor
