To update this thread, I ended up wiring a switch to manually energize the fuel solenoid coil and powering up the circuit for the inside hour meter, temp and oil pressure gauges. Installed new silicone hoses, clamps, t-stat with cover since the old cover had some pin holes from pitting. New temperature cut-off switch and of course coolant. On the bottom radiator hose, I sleeved it with a small piece of sump discharge hose since the radiator hose had a bend that deformed the smooth circular interior (Sleeve keeps the hose from deforming too much) and also to keep the hose from chafing against the fuel injection pump housing. Old hose was worn halfway through. Overall, the system works wonderfully and reliably. This saga is closed until the day comes when I decide to pull the generator out of the box to detail it and really go through everything. I believe there is a bad connection in the generator head since I am not getting the circuit to close for the generator hour meter. It is off by 600 hours. gauges also will not work unless I provided power when the fuel solenoid relay is closed. (used same power source to alleviate a possibility of backfeed)
