So my X5 is getting some miles on it and its pretty old so I want to do my future self a favor and replace the fuel pump before it strands me somewhere.

I just can't seem to figure out who the original supplier was; I know for the E46 it was Siemens/VDO. Spending $300 or so on a Genuine BMW pump makes me cringe.

Where do you guys get your fuel pumps?

Thanks.
