Worthless
Check valve leaks right out of the package brand new, and the nibs are poorly formed. Bought it to replace one which had one of the pipes break - 26 yr old item holds better vacuum then this new one!
Bottom Line No, I would not recommend to a friend
Does not work out of package
Purchased July 21st 2020. I opened the package and could hear something inside the check valve rattling. Thought was normal but hooked up to my Automotive Tune Up and Brake Bleeding Kit aka Vacuum tester and this will not keep any vacuum at all. It is non functioning out of the box. Will be returning for refund.

Garbage
Dormans products have become worthless over the years. This thing will not hold vacuum brand new. Ugh!

Unless
This part didn't work straight out of the box. The ball style check doesn't seat at all and might as well just used straight tubing with out this piece junk. Do yourself a favor and buy the motorcraft part and save the hassle

Does not work out of the box - Tried 2 of them
These parts are built with no spring inside. The internal check valve will only close if oriented in one direction and only if you tap the side several times. This part is useless in the vehicle.
