Default low vacuum wanting to add an electric pump for better brake booster performance

I'm only getting 11 inch of vacuum to the Brake Booster. I just purchased a 12v vacuum pump online. I know there are plenty of racers on the forum that may have done this. Where did you mount the pump and can you post a few pics?

Thanks

What pump did you end up acquiring? All the original GM part numbers for their early diesel cars have become unobtaninium.

Well it certainly looks the business! While I’m not planning a big cam or going for pressure I will definitely follow your results if you add updates.
I’m thinking those isolation mounts are indicating a bit of vibration when it’s running. And since hose is volume you’re probably going to want to be as close to the booster as possible. Going to be interesting.

the one from Summit Racing was $309. lets see if this works before spending that kind of coin.
