Advice on Delphi Fuel Rail Part Number
 

Hi,

I have a faulty Deplhi fuel rail. The part numbers on the part are: B47KA.... R9144Z130A...657Q9D280AA , it's of my X-Type Diesel 2.2 (2008). I am trying to source a used spare part. There seems to be plenty on the Net. but the numbers differ in certain areas. Which are the critical series of numbers or do all the numbered sectors need to be the exact same?
