Gas Problem

ive posted this before but didnt understand what to do about it, I have an 04 G35 coupe automatic,,, my problem is that im filling up my car with about 8-10 gallons i tried everything possible to put more gas in to it but nothing, and the gas gauge reads full,, and im only getting about 100 miles per tank,, what should i change,,, is it the filler or one of the sending units (if so how do i know which one?)..

As I and others have already posted, there's no way to know without taking it to your dealer and having them check it out. Knowing whether the sending unit(s) is(are) out can only be determined by testing the electrical resistance on the units, which is not something you can easily do. Replacing the shutter valve requires emptying and removing the fuel tank, which is not an easy DIY.

Isn't your car under warranty? If not, bring it and tell them about the TSB and ask them to cover it, or at least give you a break since it's a known issue. You're not going to fix this on your own.

I had the same problem ( 04 6MT). I took the car to the dealership and they said the gauge cluster was messed up. Dealer fixed it under warranty.
