Saginaw "P" style pump

The "P" style saginaw pump is like that which is found in a HUGE number of oem cars and trucks. Very often it has an attached, integral fluid reservoir, and is called the "can-o-ham" pump because the teardrop shaped reservoir is reminiscent of the shape of an old-fashioned canned ham. There are also variants that have a more circular or round shaped integral reservoir, along with a secondary remote reservoir - most notably pumps for vehicles such as 1 ton 4x4's and diesel trucks that use hydro-boost brakes. Depending on the exact model of the pump, "P" style saginaw pumps are rated for anything from 2.4 to 3.5 gallons per minute (gpm) flow and 1100-1450 psi pressure. The importance of flow and pressure ratings will become evident later on in the "system design" section.
