Agreed. 45k on an 11/06 build with non-recurring and very minor symptoms. If it was simply a QC problem in pump manufacturing, this problem would have been easy enough to sort out. The fact that the same pump that lasts for 5 or 10k mi in one car will last over 50 in another is suspicious to me.

A simple parallel - take fuses. When a fuse blows, you replace it. When it blows over and over and over, you're not simply replacing fuses. You're looking for what's causing the fuses to blow. The probability of getting defective fuses is a lot lower than the probability of some externalities causing fuses to blow.
