Stainless Steel Brakes Corp. also has an electric vacuum pump.

If you are going to make statements representing facts at least get the fact correct 20 " is the industries suggested standard @ idle..

This is directly from the website that you posted:
How much vacuum is needed to operate a booster properly?
For a power booster to function properly you will need at least 18" of vacuum at idle in park. Anything lower will give you a hard pedal.

I have personally seen (with the vacuum gauge) a vehicle that have had as little as 15" and still work very acceptable.

Gast makes a 12vdc vacuum pump for ambulances. It's very reliable and quiet. I think it runs about $150. Thomas also makes a good one but it may be pretty pricey. A google search will probably find some industrial suppliers that sell them.

The early 80's GM pump is pretty rare and expensive when found. Think it was in GM's early 80's 2.2L (Cavaliers?).

good one, the price sounds right and the fact that it is quiet is another plus, that was the one thing about these pumps that was a turn off , noisy, but for me I needed the vac and after the car is fired the exhaust is so loud if covers it ... however I am going to look into this product I am sure the noise is a consideration when it comes to ambulances thank again for the input....

looks like :
Miniature Diaphragm
10D1125 Series is the ticket here

Summit has several pump kits listed in their catalog.

We are installing one in a 1966 Impala that we installed one of the new 427 crate engines in. That 427 crate motor is fairly radical and doesn't make enough vacuum at low speeds.........the thing goes like jet-stink but it takes both feet to even slow it down!!

We should have it installed by the end of the week so I will post the result.
