Replaced fuel pump on my 2006 X5 4.8is. Failed at a stop light last week. Pretty straightforward job requiring a 10mm socket (4 nuts) and a hammer and large screw driver to spin ring holding pump in place.

Took me a few minutes to figure out how to get new unit to sit properly with new gasket installed. It wouldn't press in all the way. Fix was to press gasket in place with pump slightly out - once gasket installed pump unit pressed right in.

On a happy note fixed the rear seat heater too. Turns out the harness was unplugged for some reason. Plugged it in and voila - warm seats. Easiest fix ever!
