Gas gauge help please.... Car died

I think that there is some problem with the 370Z fuel gauge. It is not very accurate when it gets down to a 1/4 tank or less.

no doubt the fuel gage sucks. in mine the low fuel warning will come on anywhere between 2 and 4 dots never the same each time.

one time i walked on the wild side and drove with no dots showing and all the lines showing for at least 15 miles. whos knows how many gallons are in the tank when the first warning comes on.

I normally fill up at a quarter tank, and when I got to that the first week, I decided to get gas the next day. The next morning, I had an eighth of a tank showing. Apparently the other 1/8 evaporated! It doesn't seem very consistent down low.

so i just called the dealer and my car is done and nothing is wrong with is.. go figure. haha ill just make sure i dont let it go below 1/4 tank

At five (5) dots I fill-up and it takes ±13.8 gallons; the 370Z has an 18 gallons fuel tank.

My gas gauge goes nuts sometimes after some hard acceleration. Its keeps thinking im driving at full throttle everywhere and the dots just tick down every 5 miles or so. Then I get gas and find out I had like half a tank left. Its really really annoying.

this is fuel starvation, not a running out of gas situation. In hard right turns, the fuel must slosh or something and doesn't get into the pickup. I've been towed off the track before not knowing what happened, and I'm fairly sure that had I just shut the car off and restarted it, the fuel gauge would have reset to half tank, where it really was.

btw, exiting the carousel at Road America at 5500 rpm in 4th gear, it is happening to me occassionally with 1 dot not lit (basically full tank!), and always with 2 not lit. major PITA!

Spearfish rode with me today and got to experience it in my car as a passenger. It can be scary at 100mph with someone right on your bumper and you unexpectedly slow instead of accelerate!

What he said. If you look under the car the gas tank is shaped like an upside-down U with the driveshaft running through the middle. The problem with this set up is that the pick up is only on one side of the U. This makes it very easy for all the gas to transfer to the side of the U without the pickup and cause fuel starvation.

If you fill up when the warning shows, you can get a good idea.

Maybe it needs a pipe connecting the two halves?
