Selecting the correct Type II PS pump

Q: Can this system be run on a mini power steering pump with remote reservoir?

A: In most cases the answer is yes, as we have many many satisfied customers successfully running the hydraulic brake assist systems using mini pump setups. It is however absolutely critical that the remote reservoir be of a well engineered design that aggressively promotes de-aeration of the power steering fluid. The mini pumps themselves are much more aggressive in their operations as a result of being substantially downsized. Because of this, foaming of the ps fluid is much more prevalent in these systems, and may require substantially extended periods of run time to fully de-aerate. Most "older style" full size ps pumps with integral reservoirs are far superior for use with hydraulic brake assist systems. Given a direct choice of running a Saginaw P series pump versus a mini pump setup, the venerable Saginaw P pump is the "hands down winner every time". In some cases there simply is not enough engine compartment space to run a traditional pump, requiring the use of a mini pump / remote reservoir setup. If space constraints dictate that a smaller pump must be fitted, we prefer the usage of a Saginaw P "traditional" type pump, using the later model GM truck remote reservoir style sheet metal housing (as shown here) in conjunction with a well designed remote reservoir.

Which is why I chose to use a big pump.
