    That looks like the one that runs down to the AC section. Good luck. There was a few months ago, a guy in flebay with a 30 kw he wanted to sell parts off of.

    If you have all of the old plugs, you might try an aircraft avionics shop. All those small white wires look about the same size used in airplanes, plus they should have a way to imprint the numbers on the wire.

    You could buy a scrap gen set for the price you pay to have a new harness made.

    There are only two standard wire sizes for that section.

    What is wrong with your harness?

    Whats the J/P number next to the plug on the S/P relay box?

    That would be my take on it. It will still work, and that gives you time to look.

    Mice are the bane of gen sets. I once had a total of 11 gen sets down, for mice damage, out of 24-26 gen sets. No one felt it was a problem until a 1.5 million dollar radar went up in smoke. Not just damaged, up in smoke. Then our foolish HAWK WO, brought in cats. No more mice, but the cat brought on its own problems. Hundreds of dead mice. No problem as long as the snow was still on the ground. But when it melted............... Oh boy, did it stink. And then the stupid cat had kittens.

    Take some more pictures.

    Looks like the fuel filter, primary is missing. The hold down bracket for the speed switch adapter is missing. There is a hole in the fuel tank top, I think it's for the fuel return system, missing. The two wires should be for the heater system, and are not needed unless you have one installed. Yes, take more pictures.

    For the fuel system, there is two ways to look at it. One, find the right parts, and install them. Two, create your own. The old system consisted of two fuel filters, and a water separator. Good clean fuel is an engines best friend. I always liked the twin fuel filter idea, but technology has improved in the last 40-50 years. So a good new type filter, with filters that are easy to get, sounds like a good idea. I am very high on filters systems with a clear bowl on it, so so can SEE what's going on with your fuel. And a fuel/water separator is something else I like. I think going this way might be best. Unless you just want to have it like it came from the army. I would think you could come up with a system that you could install on the set, and not have to take out a loan.

    You our have a steel tank. It needs to pull it out, and inspect it. It's easy. Disconnect the hoses, fuel filler tube and fuel level sender. Should be a ground there also. Then remove the rear lower panel, under the control panel. Pull out the tank. Take a gander in it and see if it's rusted badly. That's why the army went to plastic tanks. I would pressure wash it. My boys came up with a fine way to clean them. Put the tank in a truck bed. Fill the tank up with water, 3/4 full, add a gallon of simple green. Then put duck tape on every hole. Got to clean the surface where the tape will be. Then drive around. For a while. Pump the brakes every now and then. We always put 5-6 tanks in a truck, then sent the youngest soldier out into the desert for driver training. Pressure was when you get back to the barn.

    Take more pictures.
