 cover them, make sure they've got at least enough in there because what you want to do is you want to put fresh fuel in it when you go to run it. So if there are, let's say, five gallons in this tank that holds 20 or 30 or whatever, that's fine as long as it's covering those fittings. And then you can fill it up when it's time to use it. That's if it's a plastic tank. Yeah, we just don't know when you're going to need it. So you definitely want to put the additive in there.
