How do I link an external gas tank to my original tank to let it run longer between refuels?

Question

This is for a power generator that has a small gas tank and only runs for 2.7 hrs. I hear there may be a special gas cap adapter and / or setup that would allow me to link an external gas tank to the original and allow me to run the generator longer. Is this possible?

Answer 1

I'm sure it is possible. Ask where you're making the purchase if it can be done with an adapter, they might know.

Someone gave me a thumbs down :o(

If they know a better answer why didn't they post it? I hope they feel better now!
