23 Route the hose as necessary to your power steering pump's return line where it will be tee'd into via the brass hose tee shown here. The assist unit's return hose is to be connected to the base of the tee, as shown, and then the regular power steering return line will be connected to the remaining ports. This prevents back pressure that can cause issues with the assist unit. You also have the option of running this hose directly to your power steering reservoir by adding an additional hose fitting to the reservoir. Lastly, if you have a power steering cooler installed, be certain the return hose tee is installed after any such device.
