To purchase sealing rings: https://mercedessource.com/store/1977-t0-1985-diesel-injection-banjo-fitting-sealing-ring-replacement-kit If you have had to remove any of the banjo bolts you can see that those sealing rings are getting quite old... when you see scoring in the ring the ring appears to be crushed, they should be replaced to prevent leaks and to prevent air from getting into the fuel lines. Watch the video to see where they are located and how they are installed. There are a total of 10 individual sealing rings used on the fuel filter and injection pump on the 1977 to 1985 OM616 and OM617 engines. 14 are included in this kit in three different types so you will have some extras.
