I have a 79 ford f150 4X4. When I got it the ps pump was missing. I installed a rebuilt one and filled the fluid and the ps seemed to work good. As soon as I turned the engine of the fluid forcefully spewed forth from the cap(infact it blew the cap off), the fluid was all foamed up. I checked the resevore and found it basically empty and when I restarted the engine the ps did not work. If I introduce more fluid to the resevore the ps works but spews it out as soon as the engine is turned off.
Some say the check valve is bad, take the pump back for exchange. Others say steering box. Most say impossible, never heard of it.
