Long story short,

Needle was reading E.
Went to gas station to fill up.
Gas pump cut off when tank was full.
Only filled up ~10 gallons?? wtf?

Last time Ive checked, the G had 20 gal capacity.

 

1. Everybody's needles are pretty much fubar in some way (of course there are some who will say theirs is fine and it may be) But there's been many complaints about this.

2. You sure the tank was full? Mine and a couple of other peoples' cuts off far before it fills and we need to hold the nozzle upside down to get it to fill.

 

Yeah. I believe many people have the same issue and if you're still under warranty better go get that fixed. On mines it'll never reach to the "F" mark even if I tried to Pump in some fuel. So then I was browsing around the G35driver.com and found many many people with the 1st gen G's are having this issue and there is a DIY fix which cost you nothing except 30min of your time. Here's a few comparison pics of mines before and after I cleaned the fuel sender circuit board.






You can clearly see the differences and so far so good! Usually my gauge level would drop a bit more over night then creeps back up after I drive it but it stayed at the same level.

 

Yes, the gauge read full afterwards.

My gauge reads E and F just fine. I just feel that its terribly inaccurate. Could you link me to this DIY? Its worth a shot.

 

Are you still under warranty though? This consist of pullin out both of your fuel pump assembly located under your rear seat and pulling the fuel lines.

 

Mine is super fubar, drops a ton overnight but always slowly goes up when I drive. I've got an 08 coupe

 

I've only had this happen once. Removed the nozzle from the filler, let it vent for a few seconds, then resumed refueling at a slow/medium rate.

I reset the trip meter after each refuel, so have some idea how much fuel should go in based on type of driving and miles driven.

 

Unfortunately my warranty expired last month. I have a 08 coupe as well and also had the same problem on a couple of occasions. It would read E with the light on. I leave the car over night on E. When I start the car up again and drive it would shoot back up.

 

Gas Gauge WEIRDNESS ! - G35Driver

 

Mine was , My dealer replaced mine under warretny. Would read almost 1/4 and car would be empty.

 

This DIY is only good for the people that's out of warranty like myself. Don't attempt this if you don't have to.

 

Mine is fine.

It's like an arrow pointing straight to my wallet.

 

^^ lololol

 

not as annoying as when u trying to fill the tank and the pump keeps popping off.

 

Luckly I had mine fixed when I car was under warranty.
