    540i power steering pump

    after replacing my power steering lines. steering system still leaks at the pump. already replaced it once. going to u pull it to get one. no leaks at the cooler lines seems to be the crush washers or even on the pump driveshaft. has anyone had good experience with aftermarket lines? aluminum or copper crush washers? anyone rebuilt one of these pumps? is it as simple as changing a few o-rings? I am preparing to pull my motor out (again) and aside from buying a brand new pump and lines just looking at what my options are. ditching the automatic trans and was thinking of re-purposing the remote cooler I had for it for the power steering system for the pump's sake. I push my car hard commuting to and from work and frequently spin it high when Im passing. dudmd chip with 7.4k limiter. Im confident that the combination of heat and high rpms killed my last 2 pumps. looking for some input on this. any and all input is appreciated. thanks guys.
