I put a yard pump in mine 2 months ago. It looked good so I just put it in, cleaned it out really well then installed it and flushed a bottle of p/s fluid through it. Works great. I was going to rebuild my original pump if the yard pump started leaking. not an issue now. Go ahead and try it the most you will be out is some p/s fluid. Make sure you use p/s fluid not a/t fluid. a/t fluid is what started my original leaking. Good luck
