Of course there is a fuel pump filter, do you know by chance what the filter micron size is? I think in a sophisticated pump like this HPFP the smallest particle can cause problems.
I've read about the finger pointing to fuel in the US etc. I cannot understand how this can be the root cause for the issues on the HPFP.
I mean to say and hope that a BMW Hydraulic Engineer sourcing a fuel pump for the ultimate driving machine better be familiar with fuel, how it is stored, pumped from low level gas stations etc. etc. etc. before giving the green light to install such pump and filter combination be it high or low pressure in this fine automobile.
my 2 cents on the fuel filter or filtration.
