Hey Guys,
I have a truck (M54) with an 8.3L Cummins, and I want to start some tuning. I have EGT, Boost and Fuel Pressure gauges installed and I am eager to play around with the pump a little. Only problem, I have no idea what controls what on this pump. I have spent quite some time on Google and turned up a whole lot of nothing. I know Bosch MW pumps were used on a lot of 6CTA engines, but from my Mercedes Diesel Bosch Tag Identification knowledge, I believe this is a Bosch M pump, but I can't find anything on these larger M pumps. Can anyone offer any help?
