What you could try in your post for help is suppling,
Vehicle make, model and year as you do, BUT also in diesel systems the type ie Bosch, Delphi, Siemens, Denso, Zexel etc.
PLUS pump type ( mechanical or electronic) and the pump number if possible as the same looking vehicle could have the same type of pump but different emission levels and therefore different components fitted. It is important.
