the diaphram reduces the shock in the pump from the injectors
closing. Air gets in the pump (IE runinng out of fuel,changing fuel filters)
instead of letting the truck idle to clear the air you rev the engine the
back pressure from the injectors closing slamms the diaphram with no
fuel to support it a crack develops and problems start.

Here's my post from page 2, regarding my February 2002 build, one of the last with the VP44

Mine never threw a code or lit the Check Engine light, it just died.
It was gradual, over the course of a couple weeks,
since there were no codes, it took a couple trips to the Dealer for it to finally exhibit symptoms in front of them.
got it replaced at 4,000 miles on the clock.
Lift pump was and still is fine, 40,000 miles later.
