I have put a new steering pump on my 2002 f250 and all new hydraulic hoses. I plan to install a steering pump filter on the system to help protect it from anything that is not steering pump fluid.

There are two intake ports to the steering pump. One is near the bottom of the pump and takes fluid from the steering pump cooler after it has left the steering gear. The other intake port is near the top of the pump and takes fluid from the booster.

My question is - which hose would be better to put a steering pump filter on? Is there anything wrong with putting a filter on both? I imagine the first intake hose is constantly circulating fluid and the other only circulates it when the steering wheel is used.

 

The return hose is low pressure so that is your best choice. I wouldn't cut either of the high pressure hoses. Many aftermarket PS pumps have an internal magnetic filter...I think the OE pumps just had a screen and it eventually gets clogged over time. Took my truck avout 300k miles before the screen clogged enough to inhibit performance.

My $0.02....

 

There are two return hoses to the power steering pump and I was wondering which one should be used for the filter.

 

Shown somewhere in this article is the one I used:

That will be my spring project. Thanks ...
