I just replaced the power steering pump on a 80 corvette. Upon starting up the car and testing for leaks the fluid came pouring out the top of the pump. After a little while it stopped and I refilled it again and tried it out again. I am still leaking power steering fluid but not out of the pump. I should mention that I also replaced the high pressure line and see no leaks coming from there. I know that these cars have a problem leaking power steering fluid at the slave cylinder. there are several other of what appears to be high pressure lines connected to another part of the slave cylinder assembly. It does appear to have a small leak but not bad enough to be pouring fluid out as it now. Have I done something wrong during the installation that would have caused power steering fluid to back out the top of the pump. Any tech help I can get would be greatly appreciated!

It sounds like you might have air still in the system.  You did have the cap installed on the pump reservoir while you were bleeding the system?  Did you remove either of those short hoses between the control valve and the steering cylinder?  If your car is still original you should probably just go ahead and overhaul the control valve and cylinder like I did then it will probably cure any leaks in your system.

I did no bleeding of the system at all. I wasn't aware that was required doing a power steering pump. I will try your solution and let you know how things went. Thanks for the tip!!!!

To bleed the power steering system you need to turn the wheels both way. don't go to the stops, that is what causes some of the problems you described. eventually the air will work its way out. Good luck
