I've managed to order the wrong I/C pump, the pump that I ordered was an update to Bosch 0 392 022 003, part number 0 392 022 010. Supposedly our stock pumps, Bosch 0 392 022 002, are nearly the same as the Bosch 0 392 022 003 except for the connection and the inlet and outlet size. Supposedly the Bosch 0 392 022 010 is for V12's only but I know it has been used on at least one 2002 C32 AMG as a replacement to the Bosch 0 392 022 003 which only some of them were fitted with, supposedly it has similar flow rates to the Johnson CM30. How much do the inlet and outlet size matter for the vehicle, if I was able to get this pump onto my car would it likely cause damage? How does the size of the inlet and outlet play into the pressure that the pump puts out? I feel that there are too many factors that I'm probably missing for me to decide that this is a reasonable or downright bad idea. By default I assume bad idea, but I'd like to know what others think about it.

[B]Solved: I believed that I had made a mistake when ordering this part due to inaccuracies in the information that I was finding on these pumps through forums and google. The stock I/C Pump is Bosch 0 392 022 003. For future reference, the Bosch 0 392 022 010 is compatible with our cars, without modification. You can find them cheap on amazon.
