Hi sorry to drag this up after 2 years but am having similar problems, do you have a part code for the pressure valve on hpfp ? Can’t find one anywhere,

George Calota thanks George, that’s good news as that’s what I’ve ordered, so is that the pre supply pressure sensor as well?

[@georgecalota5511]

@@ttshinykit yes, in N47 engine the fuel control valve on the HPFP (the Parts you ordered) acts as a pre supply pressure sensor as well
