Can I add Sea Foam to the fuel tank of my Winnebago Solis to clean the generator that runs off the same fuel tank? [SOLVED]

Good question. The best way to clean an RV generator that runs off the same fuel tank is to get a small gas can and fuel line and hook up the generator to that. You can add a high concentration of Sea Foam to that small can and run it through the generator. That will be much easier and faster to manage the treatment ratio and overall cleaning results

Here are a few resources explaining how to do it:
