Has anyone ever added a mechanical oil pressure gauge in parallel with the electric gauge sender on their W126, W124, etc. diesel to see how accurate the electric gauge is? I'm doing some additional work on the plumbing for my low oil pressure alarm and am thinking of adding an additional gauge to my 1987 300D Turbo (W124, OM603). Just wondering how the existing electric gauge will compare to the mechanical one.
