ok well that is what I thought.

 

What Im talking about is when the tank is empty, guage is on E, and it wont let me put more than 3 gallons in. That is frustrating..
I will take it in.

 

I can't even imagine how this is even possible if you're not using the auto-shut-off feature the gas pump has. Then again it hasn't happened to me. I always top off, and when the auto shut-off goes off, I basically pull the nozzle almost all the way out and continue to pump slowly to top off. I don't contest your claim/s but I can't see how it is even possible if not using the shut-off feature.

 

There is a small hole with a tube attached in the nozzle of the gas pump that allows autoshutoff when the gas reaches it. This prevents air from reaching the sensors in the pump and it shuts off the gas flow. The autoshutoff in the gas nozzle can malfunction because the previous user topped off his tank and refluxed gas into this feedback tube. You can also have this activate prematurely because you have a "vapor lock" in your gas tank causing the gas to hit the bottom of the nozzle before the tank is full. This can happen because the nozzle is positioned so that air and vapors cannot escape. You also have a vapor recovery system in your fuel system. This captures the gasoline vapors during filling and normal evaporation into a charcoal canister that ultimately gets purged and burned by the engine. If you overfill your tank, you can flood this canister. There is also a fuel pressure sensor that feeds back to your PCM (on board computer). If this is defective, you may not be able to fill your tank. So, you can have problems filling your tank because of
1. defective gas pumps
2. an overfiller using the pump before you.
2. poor technique using the pump.
3. a problem with your fuel recovery system or sensors
Also, overfilling your tank is bad for the environment, your car, and the next guy at the pump.

 

My car had the same problem, it not worse. If my tank was above 1/3, it would not take additional gas. I had to drive it to almost empty to get gas in it. I took my car to the dealer and they replaced the entire tank assemble and related modules. Crazy.

 

OK, I've pumped gas the same way for 20 years, and it's always worked fine, so I don't think it's a gas pumping technique problem ;-)

Question, if the guy before me topped off and "refluxed gas into this feedback tube", then would that pump allow me to pump in about 7 gallons of gas into an empty tank before it refused to pump anymore, no matter how I fiddled with the nozzle, or how much I expressed my feelings about the whole operation??

 

I dont have my 05 yet, still on my 04, but if this happens, what exactly do they do to fix it? Is it a hard task? How much time?

 

Especially if this is a new problem, it does suggest that you have a problem with your car. My comments were sort of a general lecture. Your fuel sensor that tells you how much fuel is left is different from the fuel pressure sensors. Regardless, they should be able to diagnose whether there is a physical problem or not (such as a blockage in one of the lines) or an electronic problem fairly quickly and the repairs should not be complicated. I am sure none of it will be particularly cheap, but then you did want a status car, didn't you? LOL.

 

Mr.G-Thanks-very interesting information and well-explained. (I am not having a problem).

 

Alright, well said. Let's be thankful we have a 60,000 mile warranty period.

 

Same here. Ok, I have been pumping gas in cars since 1995. I have never encountered this problem..
hmmmm....
Im kind of thinking it has to do with this car.
Yes. I will be taking it in.
Yes. They will fix it.
Yes. I will turning it in at lease end.

 

Just filled my tank up for the second time since I bought the car, and actually topped it off (my habit). When I got back in the car, the guage showed 1/8 of a tank short of full. After driving 5-miles to my home, it shows I have used 1/4 tank of gas!!! This can't be right. I may be taking it in to the local Infiniti dealer and having this checked out.

 

there is a tsb for this. http://www.infinitihelp.com/Infiniti...G35/2005/1.htm

 

If the gas nozzle is constantly clicking off while you are trying to fill the gas tank, perhaps it may be a faulty shutter valve, which is located in the fuel tank. There is a recent TSB out for this issue. I had mine replaced last Wednesday. Everything is working fine now. I trust this is the same issue, which some of you are dealing with.

See TSB no. 05031 dated 6.14.2005

Good luck!

 

Actually, here is another related thread, which I had posted earlier in the Coupe section.
