KRC’S EXCLUSIVE
CHANGEABLE
FLOW VALVE
TECHNOLOGY
www.krcpower.com
KRC offers the only pump with changeable flow control fittings. KRC pumps
are shipped with a standard flow control fitting that will give you excellent
feel and assist in 90% of all applications. The standard -6 flow fitting has no
identification mark on the hex. All optional flow fittings have an identifying
mark stamped on the hex, and they will allow you to change the feel in your
steering (see chart to right). The more flow your steering system receives
the easier it will be to turn the wheels. If you increase the flow too much, the
road feel in the steering will go away at higher speeds. Higher flow fittings
are required when using steering quickeners or 3.4 inch per revolution, or
faster, rack & pinions on short tracks with tight turns. Lower flow fittings are
required to put feel and stability back in the steering on tracks with long
straightaways. Cars on super speedways can use number 4 through 7
fittings, while a 1/4 mile track open wheel modifieds with 2-to-1 steering
quickeners could try a B through E fitting. When selecting a flow control
valve for a race track only car, the driver should use the valve that feels best
at race speeds. On street driven race cars, you must consider finding a
happy medium between the ease of parking and highway speed stability.
Optional flow control valves are available individually or in sets of 4 from
KRC or your local dealer. In high vibration applications you may want to use
a steel flow fitting. To order a steel flow fitting change the 3 in the part
number to a 4.

Power Steering Hose Tech
Power Steering Hose Kit FR1610
• Crimped fittings on all pressure ends
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.
