According to Wiki

As of late 2009, the low pressure fuel sensor has become suspected of causing some premature failures of the HPFP by engine tuners such as AMS and CP-E.

Any specific on the root cause design or manufacturing wise? It is the pump that can no longer build pressure? Is it a an internal leak because of a seal is not strong enough or corrosion? Anybody has pics or drawings?

It boggles my mind that no root cause stands out at this point.
