@Chainbreaker SeaFoam should be fine. I have done the slug of 100% SeaFoam and it can make a real difference. Personally, I would keep adding SeaFoam for a while just to remove any hidden gunk and keep the gunk from fouling things that you care about.
I have used Opti-lube XPD and Summer + in the past. You might be aware that both products use biodiesel (5% & 3%, respectively) to enhance their lubricity. That lubricity is great, but for generators, I would add a biocide on top of the XPD to hold the line on algae/bacteria growth in the tank, especially given what you have had.
Given the age of the engine, I think that it will not run well or rather long on ULSD without a lubricity additive. If you have access to renewable diesel (not biodiesel) in your corner of Oregon, I would use that in your generator. If not, pick your favorite lubricity additive and use it in high enough concentrations to bring the ULSD back up to "full sulfur diesel". Your injectors and injection pump will thank you.
All the best,
