FOR YEARS I THOUGHT I HAD A 24 GALLON TANK BECAUSE THE LOW FUEL LIGHT CAME ON AFTER ABOUT 22 GALLONS USED. WHEN CRAWLING AROUND I DISCOVERED 34 GALLON TANK. I NEVER KNOW HOW MUCH FUEL IS REMAINING IN THE TANK.NEED HELP.

I used 3/4 of a tank of gas in 25 miles. From what I've read on the internet, New very expensive parts are avaliable, but don't fix the problem. WHY THE HELL BOTHER!! Come on GM fix what ya sell. I'VE already spent a lot of money to get the check engine light to stay off, too much alcohol in the fuel was the problem!
