Generator question

Thanks. I went through the manual last night. So I am up to speed on what to do if a problem comes up. I did check for codes but had none. I did drain a bit of oil out. It was to the top of the full mark on the stick when cold. When I checked it hot initially it was to the top of the opening. It looks like they want it to the full mark when hot. As of right now it’s running fine. So we will have to see how it goes on the next trip. That’s the only issue is when it happens I’m on the road. I may grab a fuel pump so I have it with me. It sounds like the pumps are an issue. Someone asked the hours, it has 316 on it. Has a new filter and fresh oil before I bought it. Not sure on the plug. But knowing how the previous owner was meticulous in the maintenance I’m sure it was done.
