I think I have one, loaned it to a buddy for mock up purposes. According to him it was the best version for compact tractor pulling, he got his info from Harts's. It's a good used pump. What are they worth?
That's what I need them for.
I intend to retrofit the A pumps to the kubota and yanmar engines, hoping that making a ready to run kit will help out some of the guys wanting to get into the class.
