Had the same problem had local Bosch shop order the gasket kit for the pump when i asked where the rectangular one was, he said there never was a rectangular moulded one that the old one just got that way from being clamped in there.I used the one that came in the kit and it worked ok ,i had the pump on the bench so easy to do. I also read somewhere that the o ring from the oil filter cover will work but i didnt try it and i am not sure if that was for a 5 or 6 cyl pump. Don
