I have a Onan Gold 7000 generator. Runs fine normally, but sometimes when traveling in hot weather it develops vapor lock. When it happens, it has been when temperatures outside are above 97/98. We...

I agree these problems are heat related. I have an Onan 2800 in my PleasureWay class b van and find it runs flawlessly if the outside ambient temperatures are not really hot like maybe 95 degrees Fahrenheit or below. Once the temperatures climb and the generator has run for awhile, it will shut off abruptly but can be started up again and run for a short while like 10 minutes and shut off again. After it has shut off and not run, I'll get a very strong smell of gasoline for about an hour or so. I think the carburetor is so hot that it is percolating the gasoline out of the bowl. When running the generator in these hot conditions I find that if I remove the black metal cover on the front and run without it in place, it happily runs along without stopping nor any percolating of gasoline due heat soaking. Maybe some sort of cooling fan can be installed? But where?
