The one in the back of the fuel pump is the pressure regulator. What type of injectors are fitted? Are they Bosch or Delphi?
Not sure I didn't see any markign when I swapped them but then I wasn't looking. I have found the other fuel rail so I will swap the pressure sensor tomorrow as 2 can't be faulty and while I do that I will check the injector make.
Cheers for the reply....
