On the left of the picture is a plug in the intake manifold which looks like it has an electrical connection stud on it but is also posdsibly thermal or baropmetric in nature. I simply don't know.
That line is connected to what looks like a solenoid on the bulkhead, the other port is connected to the injection pump overflow 'fitting', probably the always-open part of the valve.
I'm keeping this system IF it is useful, otherwise it comes off like the fan-clutch in my other posting today. And just like with the other posting, if I had the manual that would help a lot, but I don't.
