In trying to remove the fuel pressure regulator from the high pressure pump I’ve discovered my van is the EGR version, contrary to what I said above. I don’t think this impacts on my current non starting issue except that it is making access to the pressure regulator more difficult. On the attached photo the pressure regulator is the blue blob and the red pipe is part of the EGR circuit which is something (else) I know nothing about. My question is; can I just remove these pipes to improve access to the regulator?
