FWIW, GM has been using vacuum pumps on most of their diesels as well as some of the smaller displacement gas engines that needed extra vacuum for heater control diaphragms, and vacuum boosters. The 5.7 diesel that came out in 1978 had a vacuum pump in the distributor hole, other applications had belt driven pumps. GM W bodies (GP) had electric vacuum pumps for the brake boosters also. These pumps were made by Saginaw. If you don't want to use a ford part, plenty of GM cars came with vacuum pumps too.

The systems have been on fast Mustangs as STANDARD EQUIPMENT since 1996. So you are a bit behind in your info and need to do some research into the systems. Hydratech makes a large number of systems for retrofit on older vehicles. Tom V.

hydro boost
Look into Astro Van hydro boost. Have one on 65 GTO with front disc. Works great and not to hard to install. You need power steering and bend or modify the brake line.

Her is what I did. These pumps come with the air in and out in different locations, I chose this one because it fit my lay out. This is a Ford pump. It was designed for the vacuum brakes on a truck. Some out there look the same but supply much less vacuum. Most of these pumps made for GM only supplied vacuum for HVAC controls and cruise control so keep that in mind. It came with a flat pulley, I changed it to a GM to help keep the belt located.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
