Ive been told that its some sort of valve for the power steering. Its about an 1 1/2 tall and its has some sort of little tiny screen on the inside of it on the end. I was told that there is a spring that should go with it, however i lost the spring. So i bought a used ps pump just go get the spring out of it. Well i got it today and i couldnt locate where this valve and spring would have fallen out of. The pump i got today is a 93 and i have a 95, could they be differant?? If they are the same then where in the heck did this spring and valve come from?

 

Come on i really need this information before i put my car back together.
