Works great so far
Purchased this pump for an 09 Cooper S JCW edition with 125k miles on it due to engine stalling immediately after start up. Installed the pump myself approximately 3 weeks ago from date of this writing and the starting issue has disappeared. Hopefully it lasts, so far very happy with the results.

Engine fired up on first crank

Installed in a 2009 Mini CooperS Clubman, went in without a glitch and fired up on first crank. Cold start issues are gone and throttle response is restored. I've driven it a few days now without any issues - so far, so good! 3-Month Update - 100 days of daily driving and the pump still works fine, still no problem with cold starts or acceleration. 10-Month Update: still going strong
