Power steering pumps require a hose with a vacuum rating of 28 INCHES/HG on the inlet side, and a
minimum ½”inside diameter. This is required to keep the hose from collapsing at higher RPMs. As
seen in Photo 1 to the left, common hydraulic hose may have a -10 fitting on them, but the inside
diameter is smaller than -6 (.265”). This will damage the pump because there is no way for the pump
to intake enough fluid to meet its requirement through such a small hole.
Push-lock hose may be the proper inside diameter, but the vacuum rating is only 18 INCHES/MG. As
the fluid warms up, this rating actually goes down. Push-lock hose will suck shut anywhere there is a
bend in it, starving the pump of fluid and can cause severe damage to the internals of the pump. See
Photo 2.
The -6 pressure hose, leaving the pump, must have an operating pressure of 2,250 psi. and an inside
diameter of .31”. Common hydraulic hose may have the proper operating range, but their inside
diameter is slightly smaller. See Photo 3. The smaller diameter can restrict the flow to the steering
gear. This can cause problems in your steering, such as tight spots in the turns and increased driver
effort.
KRC only recommends Aeroquip AQP High Pressure power steering hose with steel AN fittings.
