Make sure you have a full tank of gas and some extra on hand.

It is extremely important to know exactly how many miles you can travel on a single full tank of gas – including any round trip you might need to make.

I also suggest having at least 30 gallons of extra fuel stored in your garage. Invest in a fuel saver additive and leave the breath cap open. You might lose a little gas through evaporation, but that is better than what could happen if pressure got too high!
