Mityvac MVA660 Power Steering Air Bleeding Adapter Kit for Hand Vacuum Pumps, Fits 5/8" - 1-5/8" ID Pump Necks, Rubber, Cone-Shaped Design, 1/4" Barbed Connection, Air-Tight Reservoir Seal

I was skeptical spending $20 on a rubber cork i could probably make myself. But I bit the bullet since it fit the spec for my Ford "pencil neck" power steering pump. It fits the pencil neck PERFECTLY.Coupled with the Mityvac 8500, this worked great in getting the air out of my system.

There have been some reviews that this tool doesn’t work on GM power steering pumps with notches for the cap. I have used this several times on my 2007 Tahoe and it works perfectly. You need to push and turn until you get this adapter far enough into the neck of the pump. Also make sure your MityVac vacuum hand pump is working properly itself and can hold a vacuum.

Great. Doesn't fit a 2000 Ford Ranger.

Worked great with the Mityvac vacuum tool. Blead my power steering pump the correct way this time. Pump works so good! no PS wine whatsoever. Worth every penny.

Great Tool for what it is; I bought this to do a full flush/clean of my clutch fluid and it did the job. My '05 LS2's clutch reservoir has a shape that requires you to press down quite firmly on the adapter before you get a seal. The downside is given its depth, you have to create a vacuum to suck up some of the fluid displaced by the adapter itself. This was a major challenge and caused a few minor spills, which I had prepared for with lots of towels to prevent corrosive fluid going anywhere in the engine bay. I would've docked a couple of stars for this normally, but this isn't built primarily for clutch fluid reservoirs, so I refrained from giving it the 4 stars that it really deserved in my application.Ultimately, I recommend it when nothing else is available for a clutch fluid flush, and it would definitely work on multiple other types of reservoirs as well.Additional Info for 2004, 2005, and 2006 Pontiac GTO Owners:Try Motive Products 1100 Master Cylinder Adapter for Clutch Fluid changes

Sealed my power steering pump reservoir pretty well. I used it to pull air out of the system.

This mityvac steering fluid vaccum would not stay in place on the steering fluid reservoir. It did create a vacuum but I couldn't leave it alone with the vaccum staying on it as is needed to get all the air out of the system. I returned this item and bled the system by jacking up the car and turning the wheels which is what I was trying to avoid having to do. But if this would have held steady in the reservoir without my holding it down to do the job I think it would work great.

Why they don't give a decent product description is beyond me. To just call it a power steering adapter led me to believe it fits "most" power steering pumps. This doesn't fit FORD. After returning the product (and having to pay return shipping costs) I tried to find what would work. A Lincoln industrial PDF states:Model MVA660 (this model)• Rubber, cone-shaped design that seals pump necks ranging from 5⁄8 up to 15⁄8 in. (16 up to 41 mm) internal diameterModel MVA661• Designed for sealing GM power steering pumps with a two-tab cap designModel MVA662• Seals Ford power steering pump necks having an internal diameter of 11⁄4 or 2 in. (32 or 50 mm)I hope this helps others in knowing what adapter to buy.
