Fixed noisy and leaking power steering pump
My daughters 2008 Honda Accord 2.4L 4 cylinder that had a very noisy power steering pump which was also starting to leak. I was about to buy a new pump when I found out it might just be leaking from the hoses to the pump. I bought these O rings for the hose connections at the power steering pump, and spent 15 minutes replacing them. Pump is quiet again! The suction hose can develop a leak, letting air get into the pump which creates the loud noises.
This fix is all I needed, and was much cheaper and faster than replacing the power steering pump.

Good fit
Both filters fit well on my 2019 Honda CRV. I was able to replace without struggle. Did it on my own first time.
