Steering Pump ID Help......

Yours looks just like mine. they look just like a federal, BUT, come to find out it is a trw Thompson. After getting the wrong kits twice I went to a hydraulic repair shop and matched the big resevore O ring and the flat ring that seals the back, where the mount bolt goes through. Also noticed that a reman company or P.O. chucked the pump in a vise and buggered up the sealing area. Filed the burr down, installed these 2 new rings and no leaky8) If your pump is just leaking this may be your cure also.
