Good links. But still, Meow reads a lot about the keeping tank full thing. But if one did not use the truck for years, you might end up with 25gal of bad gas. Meow is thinking of looking to buy a few gallons of real hi octane gas then add stabiliser. As most gas here is not real gas but e10 or e15. Now that might be a good idea. the lightning needs premiun fuel anyway because of the supercharger. Will look online where they sell that locally.
