Fuel accumulator 0438170004
« on: 06 February 2021, 10:06 AM »
I've ordered and received a replacement fuel accumulator Bosch 0438170004. This is a two port accumulator and is the correct part for my 1977 6.9. Reading other posts I see that later models have a one port accumulator. The item is stamped Bosch, made in Germany, as per the pics. Surprisingly it is not painted dark green, instead it looks like it's made of stainless steel. Anybody else seen these? Can I be certain that it's a genuine unit and not a copy?

Did you order from Mercedes or is it NOS of some 3rd party site? The OEM part I got a couple years back from the dealership wasn't  made by Bosch, but some company in Czechia. Colour is right though.

My bosch unit from a few years ago was also dark green.  I have never seen that finish myself...

Bosch moved the production to another plant 2 years ago, and by this they changed to an eco-friendly coating, so accumulators of current production are silver in appearance now.
