When the CP4 lets go it typically grenades throwing metal shavings into your fuel lines and injectors. Entire fuel system has to be replaced to the tune of $10-12k if out of warranty.
Since Bosch has to know this, and assuming they can't stop the pump from grenading if it fails, you would think the OEMs would install some sort of screen or filter or something immediately downline of the pump to catch the debris. If the pump has to fail like that, so be it, but there has to be a way to contain the damage so that the fuel lines and injectors don't need to be replaced also. Make it a $2000 repair instead of a $12000 repair.
What am I missing?
