I'm surprised to see a 2011 with HPFP probs, and 4 to boot. It was the 2011 model that finally got the fuel pump that worked. Makes me think there's something else going on because even if you somehow started out with a bad version, you should have gotten the good pump for a replacement. But 4 times?
