Part # 001 586 19 07 is a new old stock fuel injection pressure regulator repair kit made by Bosch (3 437 010 021) for Mercedes Benz and other manufacturers. It fits different applications of the M116, M117, M110, and M100 motor. Condition: This new old stock part was still sealed in the original packaging until I opened it to verify condition and get photos. The bag with the washers and grommets is still sealed and the part comes with all original packaging. I’m still unpacking a large collection of Mercedes-Benz parts that include some rare, new old stock, as well as some pre-owned parts in good, tested condition. Most of my Mercedes-Benz parts came from a dealership’s parts department and have remained in a climate controlled environment.
