    I just bought a 2004 Chevy Avalanche Z66 and went to the gas station for the first time with my Ava. I waited and waited before filling up my truck because I didn't want to mix different type's of octane gas because I have no clue what octane of gas the dealer put in it. So I waited until my gas gauge was on E and my Low Fuel light came on. I went home and did a few things "took about an hour" then went to the gas station. When I got to the station I put some GumOut fuel octane booster and Carb/Fuel Injector cleaner and put it into my gas tank before I filled up my truck. I looked how big my gas tank was and it says it is a 31 gallon gas tank but I couldn't even pump 21 gallons and my fuel gauge didn't go all the way to F it was just shy of it tho. I went to the same gas station that I always got to when I am in my town so I don't understand why it wouldn't fill it all the way up.:grrrrrr:

    As far as I know all 1500 Av's have 31 Gal tanks...the 2500 have a 36 gal tank..

    If the fuel light just came on. then I think you should have at least 3 gallons left in it.. Not sure.. but 21 definitely seems off.... But then again, Chevy doesn't have a great track record with their fuel gauges.

    Is it possible that the station has a limit on debit or credit purchases. I know not to long ago most pumps automatically stopped at $75.00. You were required to re swipe the card to pump more. Just a thought.

    Ok, your gauge is telling you it's not full, so there must be a problem with:
    - the neck of the tank,
    - the hose at the pump.

    How did you conclude the tank was full?

    If the fuel was appearing to be overflowing from the neck, maybe there is a "big" dent in the bottom of the tank.

    pumps in Los Angeles have been cutting off @ $100 for me..sucks. Just about full but not quite.

    Keep an eye on the dollar amount. I've guilty of not filling up until the cluster tells me the range is LOW...

    Yeah, they all do that when you use a card at the pump. The pump control program passes the card account number to the issuing financial institution and requests a hold to be placed on $100. The pump will shut off at $100, filled, or not filled.

    We've had this problem, in Canada, for awhile (our gas is a lot higher than in the US), if gas prices remain high, and I'm sure they will, the hold amount will probably be raised.

    If you pumped almost 21 (according to your receipt) and have a 31 gallon tank then your about 10 short. If your card shut it off then considering you had a few gallons left then your probably closer to about 6-7 gallons short putting your gauge about where it should be. Hope thats your issue!!

    I wish $3.59 was the price here!! seen $4.06 here today

    After "the phantom" posted, I went back and looked at your receipt. I believe Fixer has the answer, your pump is shutting off at $75, filled, or not.

    The pumps in CT don't cut off they want all your money :lol:

    But gas here is now 4.09 average.

    I know my truck as a 27.5 gallon tank (per the sales sticker) and looking online. The way it normally works is that trucks with the really short bed 4.5 feet or something have the small tank, then trucks like mine with the 6.5ft bed have the medium tank, and then trucks with an 8 ft bed have the big one (34 or 36 gallons.

    They do that because the shorter the bed, the less space they have to put a tank. The avalanche is a hybrid design (Crew Cab + that custom bed). So the size of the tank you have would depend on how long the frame is that the avalanche is sitting on.

    I try to fill up around a quarter tank so I am usually putting 18-23 gallons in each time, avoiding the $100 limit here and never had an issue. But if you hit that $75 or $100 limit, then you will need to swipe the card again and continuing the fill up.

    I honestly never even heard of such a thing as in the pump shutting off at $75.00 or $100 but then again my past vehicles didn't have a very big gas tank so I never would go over the limit.

    Thanks everyone for having my back. Really glad to be in this community as I am a new owner of an Avalanche.

    nak, the Av is a Suburban with the upper rear corner cut off. It uses the same tank as the 'Burb

    Smoke, easy to check. Next time your at empty, refill, let it shut off and hang up the hose like you are finished. Then re-insert the card and start to fill, you should be able to top it up this time.
