1999 up ford super duty pick ups use an electric vacuum pump and they're usually on the RH inner fender near the middle by the fender. I'm currently trying to decide if I want to use my vac booster or go with a hydraboost I have. I'm leaning the vac booster since it's 2 less lines I have to run. The car stopped alright before with the stock MC so the better MC should be a big help already.
