Review: Quality part - Perfect fit! 03 ranger
Review: and perfect results. I didn't even have to pull the ... - I purchased this unit for my 2006 Ford Taurus. The fit and finish are superb. I had a leak at the high pressure output. A couple hours work, and perfect results. I didn't even have to pull the pump. The only part that's not included, is the Teflon seal, for the control valve, to high pressure line. Just $ 3.00 from Dorman. Don't forget to put some light grease on the Reservoir mouth, prior to mounting it to the pump body.

### ⭐ Wrong o-ring supplied preventing installation.
*by T***1 on July 15, 2025*

Dorman 603-900 Power Steering Reservoir for 2000 Ranger. The unit was impossible to install, due to the supplied large o-ring being too thick. I tried several times and even removed the pump. The o-ring just pushed out of the housing causing a leak. I finally fixed the issue by purchasing an o-ring rebuild kit from O'reilly Auto for $10 and using the o-ring from that kit. The reservoir slid right on and no leaks. The Dorman supplied o-ring was quite a bit thicker than the rebuild kit o-ring. Too thick to allow the reservoir to seal on the pump body.
