Worked, but not as well as the original
The pump repair kit worked, but the parts aren't identical to the Graco parts and I've rebuilt 1,000's of these. My own unit is used very little and my only issue was the check valve balls weren't as crisp as new and I wanted to replace them so I bought the whole kit. The upper packing leaked with the original spacer ring in place. It wasn't leaking before I installed the new seals and the shaft has only .002 of wear on it. Not sure what the seal issues are, but they obviously don't work as well as the original...... I guess you get what you pay for!
