Yes. Fuel injected engines require higher fuel pressures than the older vehicles with carbs. Because of the work the fuel pump has to do, it gets very hot. The manufacturers put the pumps into the tank so that the fuel in the tank keeps them cool. It is for this reason that you should not run your vehicle with less than 1/4 tank of fuel. Once the fuel level drops below that level, the pump is not submerged anymore, and it then has no way to dissipate the heat. This will lead to premature failure of the pump... Usually about an $800.00 repair.

What can you purchase to carry in your car as backup for out of gas?

It's not advisable to keep a can of gas in your car... too easy for a fire to result in the event of a crash. --------------------------------- additionally modern cars have an electric fuel pump in the gas tank. The gas is not just fuel, but also helps the fuel pump cool. Run out of gas and you can ruin a fuel pump by continuously cranking the engine. Some recommend never letting your tank get below about 1/8 tank to keep enough fuel to cool the pump. Just keep some gas in the car.
