Using the K - Tuned Power Steering Line Kit is simple. First, make sure you have the right year - specific kit for your RSX or swap application. If you're doing a custom setup, you can just use the pump fitting. When installing, ensure the line's swivel ends clear the stock mount stud. As for the note, remember this kit won't work with the FLK - OF fuel kit. Also, expect the line to be louder than the stock one. For maintenance, regularly check the fittings for any signs of leaks or looseness. If you notice any issues, tighten the fittings or replace them if necessary. Keep an eye on the power steering fluid level as well, as proper fluid levels are crucial for the system to function smoothly.
