Fuel Equalizer - what part by the vacuum and high pressure fuel pump would be called by this? Diesel mechanic's terminology.
Sounds like a term to extract more money from your wallet.
The post #3 pictures here should answer your question.I recall that there is a transition point in control after starting which Doktor A mentioned one time. I don't recall the details. Some searching wasn't very fruitful.
Found it, but it may not apply to OM612 engines.
...Got the diag from Dr. A. For the first 30 seconds or so there is a solenoid on the end of the rail that controls all rail pressure and bleed back to the return line. On 04+ models there is another control piece on the high pressure pump that takes over fuel delivery quantities after 30 seconds. So one of the two pieces is acting up and we are gonna use a DAD to find out which one. Ill let everyone know the results. Thanks!
