1965 Thunderbird Powersteering problems

[1965moscabird]

Hello All, I really need some help. I have a '65 Thunderbird something strange happened the other night. When I merged into traffic I was kind of heavy on the gas pedal, I noticed after wards I had no powersteering. I thought the belt had came off, but the belt is still on and it is tight, the pump is not making any noise and I have no leaks. Someonetold me the pressure relief valve could be stuck open any opinions? And tell me what other Ford powersteering pumps can I use? And does anyone have a powersteering pump for sale? I live in Southern California, I will pay for shipping and yes I have tried to get one from several auto parts stores but no one stocks the pump. Please any help would be appreciated. Thanks:auto

If your car has factory air with the power steering reservior mounted on the inner fender, the torque of the engine under heavy throttle can cause the engine to give on the motor mounts enough to possibly close off the return line to the pump.
Was having a similar problem on my 64. Shortened the return line about 3/4 of an inch and no more problems.
