Not evasive at all.. Because we never know what pump we will be getting from Porsche, which is where we source them from.
No pump has proven to be better than any others at this point, just know that they ALL need to be changed every 3 years, no matter the mileage if you intend to prevent failures from occurring.

The fact remains, however, that it has been in there three times longer than recommended and has not detonated.

But you don't know that.. The pumps do not have to catastrophically fail, make noise of seize to cause engine failures.. One chip from an impeller blade is all it takes to wipe out an engine.
There is nothing dumb about preventive maintenance, if yours hasn't failed it needs to be changed so it doesn't fail. I come from an Aviation background, I take preventive procedures seriously and thats why those who have us service their vehicles never have engine failures.
Like playing Russian Roulette? Some must because they do it everyday even though they know what the repercussions could be.
