I have a new rebuild Bosch VP44 injector pump from a Napa auto store that is from Echlin. I do not know were this pump was rebuild and can not get any info from Napa or Echlin. My question is about what upgrades have been done during the rebuilding of this pump and is the FPCM the newest version. The info on the FPCM is 0281010890 119118 001189 (810)
