I bought a NOS vacuum/fuel pump a couple of years back. I don't know why I bought it. It seemed like a good idea at the time. I bought it on ebay and it wasn't enough money for me to remember the cost. It came in the original box I think. I have a 12 volt vacuum pump for my brakes because I have a blower. They can be pricey if you want one that doesn't sound like another engine. I think mine is a scroll type and requires no reservoir but I'll probably put one in anyway. I think it was a little over $500.
