I believe you were reading about my oil pressure issue. I logged in here to post the same question I had on other forums... "What are the idle and nominal oil pressures on a Farymann K34 diesel?"
For what it's worth, what I have found so far...
Service manual states: Idle (7psi), Nominal (23psi)
Farymann website: Idle (1.8bar=26psi) ... We've determined this is clearly incorrect information.
Experienced mechanic: "You can probably run the K34 down to 3-5psi and not have problems." And, when asked if 15-18psi is acceptable, he agreed that it's sufficient.
My engine is running at 10psi at idle but only 15-18psi at full revs. I am trying to find out if this is "normal" or if it is not receiving enough lubrication.
Now back to your question... I have taken a few pictures will happily e-mail them to you. I'll take better ones on the weekend to show you how it is installed. It looks like some sort of T-attachment on the starboard, forward part of the engine. Out of the top is the electric sensor and out of the starboard side is a thin tube that runs to the mechanical pressure gauge and then back to the engine. I'll have to double check where the other end of that oil line returns to the engine.
I don't believe it would be difficult to install one.
