Yes, the BERG system will work with the champion according to the website. It seems to be a high quality system. Also, from the site.......
"Note* : Some generators like a few models made by Polaris, Champion, Yamaha, Powerhouse don't have internal fuel pumps so to allow the system to gravity feed you must put the external gas tank above the generator."
It is based on a siphon system. I will have to purchase two BERG systems for $180, then I will have to buy two marine fuel tanks. That's expensive to me for an extended run system.
If I go with the fuel caddy, fittings, hose, it will cost less than $150. Plus, I can use fuel caddy to fuel boat at dock.
