Once it runs dry, the engine will stop immediately from fuel starvation before any damage happens to the pump itself. As I said, my car is an 08 and I was in my gas tank this weekend. I've filled up from all sorts of places, even once in Mexico. There's nothing in there but pure gas. If there was something foreign in there (like the screw i dropped in there and had to retrieve) it wouldn't get sucked up into the pump because of the filter/screen. I've run out of gas twice in this car. Once on purpose and once because of a malfunction of the fuel gauge. My pump is just fine.

This is my personal experience on this car.

Since you've been in the tank, you're probably the most qualified person to answer this:

Where is the pump inlet? Front, Back, Center?

If you're really low on gas, and need to park on an incline, which direction would you want to park in, nose down or nose up?

The fuel pump itself is on the passenger side, directly below the center of the rear passenger seat. I can't say regarding the pickup. There is a pickup hose that I disconnected to pull the pump out and I didn't look around to try to trace where the other end of it is.

Most people think it does and will repeat things that they've heard or read on the internet (so it must be true, right?). There is no trash/water/debris etc on the bottom of the tank that the fuel system will pick up when the tank gets low. I know this for a fact because I have actually seen inside the tank on many cars, including my G37 just 4 days ago. Nothing in there but gas. Running the car low on gas does not "burn up your fuel pump". The pump is inside the tank itself and is in the gasoline. Which is always cold no matter the temperate outside. There's always cold gas running through it to cool it, as well as floating in the cold gas. If you run out completely, the car will shut off from not having fuel long before any damage to your fuel pump occurs. If everything is functioning properly, you won't run out of gas just because the DTE hits zero. As you discovered, when the cluster gauge and the DTE computer tell you the car is completely empty, there is still anywhere between 2 to 3 gallons of gas in the tank. The most miles I've personally driven is 66 after it hit zero. Our gauge and DTE algorithm is very conservative. Even if you do run out of gas completely, it wont harm your car. Just don't repeatedly try to start it with no gas in the system. Put some back in the tank and it will start up and run like normal, no harm done.

I speak from personal experience. I have been in the tank of the G37 several times. My car is over 7 years old. I've had to go in the tank to service the fuel level sending units twice to get the gauge to read correctly.
Whether or not running the tank down close to empty has an effect on the fuel pump or any other aspect is not what is important in my opinion.

Not having enough fuel in your vehicle in an emergency is very important in case of unexpected power outages and hurricanes.

Here in NJ we have had sudden road closures for hours after serious accidents. Even being a few miles from home with an empty gas tank can have severe consequences during very cold weather and a road closure from an accident.
Running out of gas is not an experience I've ever had.

This is a lesson that many learned here in NJ during Hurricane Sandy.

With severe weather predicted for later today I filled up my tank this morning even though the needle was slightly above the quarter mark

I agree. It is a good thing to have fuel in your car, especially in emergencies.

^^Any state with mountains is also applicable to telecoman's comment. I remember traveling through CO around memorial day weekend 2013. The interstate got shutdown due to rock slides. Had to divert a good 100 miles to get around it.

Similar issue as Erik

Hey guys,

I'm new to the thread and also a new 2010 G37 6mt owner. I'm having the type of issue as Erik and I think I'll try the reset the battery but I just want to be clear. When the dealer filled up my car, the range meter said I had 189 miles to E. I know it's not right but I want an accurate reading. Is resetting the ecu what I need to do?

Thanks guys and loving my car

That figure will change if you reset the computer every time you fill up

For those that think it is smart to let their fuel run close to empty be forewarned that s#it happens and can happen without warning.

When you are driving in 95 to 100 degree heat in the summer time or 10 degree weather in the winter time any serious accident that can close down a road for hours or even overnight can make your day a very bad one. Not having sufficient fuel can ruin your day.

Having the warning light on with 100 miles left is hilarious hahahaha, maybe it thinks there is no gas station within 75 miles

That would be a very smart car.
