Mityvac 4000 Silverline Automotive Vacuum Pump Kit

The Mityvac 4000 Silverline Vacuum Pump Kit is a great collection of a solid vacuum pump and a host of fittings for testing and applying vacuum on many things.
I gave this product four stars only because I think the instruction manual could have been a lot meatier.
I'm NOT a professional automotive tech, so the mysteries on the motor (especially vacuum parts) really nned some explanations beyond the dire basics.
I guess I'll learn in time. But the product is already saving me money. :)

Pros: Does the job of bleeding the car's brakes
Has a lot of attachments for various hoses.
Cons: The gage face is plastic and is destroyed by contact with brake fluid. For a tool whose main use is brake bleeding this is serious oversight. The plastic case and parts have a strong chemical odor, that persists after removing from the wrapper.

Great tool!!!
If you know how to use it, which some of the other reviewers apparently didn't. No better vacuum pump on the market. Kit is great, has pretty much any adapter you could ask for.

I bought this vacuum pump to diagnose my 1982 Mercedes 300D's vacuum system. Door locks were not working right and the engine wouldn't shut off. This pump helped me repair the system, and again and again. Great tool.

I also like all the hoses, adapters and attachments that come with it. I haven't met a vacuum tube on my Mercedes that I can't hook up to.

Great kit I have used it for the following, Adjusting the level of automatic transmission fluid after changes. Bleeding my brakes by myself, testing EGR valves and Vacuum lines on my cars. Drawing out oil that collected in my spark plug ports (Tauras SHO). Wished I had one of these years ago.
