Something very weird going on here. I just hope you are testing these pressures correctly. You don't usually test pumps after fuel filter - tells you nothing other than what the pump spec is for pressure. What you need are WUR pressures and System pressure. If you really do have a system pressure of 9 bar, you won't have enough shims in the FD to reduce it - my guess. Probably only 2-3 shims and about 0.5 bar to loose. But worth a look first. Take all the shims out and see what you get.
