Ok, some screen shots with commentary...


See how Fords response to NHTSA investigation shows that scar ratings above 460 will decrease the life span of the pumps. US specs 520 max. Now on to the Bosch presentation...


You can see from Bosch tests from 2002, 80% tested exceeded 460, with some samples as high as 636. The included graph shows how this will relate to life of fuel pumps.
As stated before, Bosch has added a wear package to the pumps for Ford to extend the life when using our **** fuel. This doesn't address the nature of the CP4 that allows it to send metal fragments through your fuel system at almost 30,000psi when it does fail.
Failures like this are almost non existant in the CP3.
