Power Steering Hoses
Things we all need to know and do when it comes to power steering:
1. Clean your system before you install your rack and pinion and your pump, reservoir and hoses.
Contamination will kill your steering and cost you $$$.
2. After installation, do not start or crank your engine until you fill the system with high grade power
steering fluid (do not use transmission fluid). We recommend KRC power steering fluid.
3. Follow instructions to bleed your system to remove all of the air.

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.
Also make sure the -10 feed line from the reservoir tank, remote tanks only, has a ½” inside diameter.
Some companies have been importing tanks to the U.S. that have a 3/8” inside diameter. This will restrict
flow to the pump and will damage the pump within a few races.

KRC offers the only pump with changeable flow control fittings.are shipped with a standard flow control fitting that will give feel and assist in 90% of all applications. The standard -6 flow identification mark on the hex. All optional flow fittings have mark stamped on the hex, and they will allow you to change the steering (see chart to right). The more flow your steering system the easier it will be to turn the wheels. If you increase the flow road feel in the steering will go away at higher speeds. Higher are required when using steering quickeners or 3.4 inch per faster, rack & pinions on short tracks with tight turns. Lower flow required to put feel and stability back in the steering on tracks straightaways. Cars on super speedways can use number fittings, while a 1/4 mile track open wheel modifieds with 2-quickeners could try a B through E fitting. When selecting valve for a race track only car, the driver should use the valve at race speeds. On street driven race cars, you must consider happy medium between the ease of parking and highway speed Optional flow control valves are available individually or in KRC or your local dealer. In high vibration applications you may a steel flow fitting. To order a steel flow fitting change the number to a 4.
