Hey all, I am working on tracking down a rough hot idle on my D. While doing some testing, I found my primary pressure to be about 4.75 bar. The book says it should be between 5 and 5.5 bar. Should I be concerned? I know the pressure was over 5 bar a few years back when I rebuilt my fuel system. Today I am going into the tank to check some things out. I replaced the accumulator yesterday and I also have a spare fuel filter laying around that I might pop on. If the tank is OK and the filter is new, the only other things could be a bad fuel pump (it is a few years old, prob less than 10K on it), or the primary pressure regulator needs shims added/subtracted... right?
