A 1,000 gallon tank holds 800. That’ll last one week running 24/7.

Which would have been just how long she would have needed it until they got the power back on in her area...
And I'm pretty sure she could have gotten the tank refilled within a day or two of the hurricane ending if she was depending on it. My comment above was just about how long a tank would last when it's just doing it's maintenance runs.
You are right about changes being needed to switch between natural gas and propane. From everything I've read it's a fairly big job, if the parts are even available for a particular generator. It sounds like you need to go one way or the other.
I was just pointing out that it's not uncommon for natural gas to be turned off in an area that may have already lost power.
