The gas station pump might have been metering wrong. Have you ever put that much in the tank again? I have never gotten more than 18.25 to the very top of the neck.EXT models also had a larger tank. Mine has the 18.7. I have driven as far as 50 miles with the low fuel light on. Now, I swear this is true, It took 19.3 gallons to fill it up to the neck. Can you say "fumes"? However, I would not recommend that to everyone. I just know my TB.
Have an 03 Trailblazer and was wondering how many gallons does my gas tank hold and also is there a low fuel indicator and if there is, how many gallons are left when it comes on.
It's possible as rbarrios said to have 2 possible sizes....you can either watch the pump and if you get gas when your light is at E and it fills 18-19 or more at E then you obviously have the 22 gallon, if its only takes 15-17 gallons on E then its the 18.7 gallon tank......if you do this method I would watch 3 fill ups to see where it stops at seeing how it was already said that the gas stations pump meters might be alittle off sometimes....Since you have an 03---- you have 2 possible tank sizes...
Early models had the 18.7 gallon tank. Somewhere thru the production- they changed to the 22 gallon tank.
I have an 03- and it has the 18.7 gallon tank.
When my low fuel light comes on- and I drive to the gas station-
It will on average take 16.7 gallons to refill.
Meaning that I still have 2 gallons of fuel left in the tank when the light comes on.
Once your light comes on- I recommend you go gas up- and take note of how much it took...
Over several tank fulls- youll be able to approximate how much gas you have left.
Same frame so I am thinking yes however the hoses might not reach if the pump is further away. As for fitting a 25 gallon tank into a SWB trailvoy I don't that can be done. It's too short.I have an 02' TB with 18.7 gallon tank, does anyone know if it is possible to upgrade to the 22 gallon tank? I drive long distances, it would just be nice to stop less frequently.
I have a 06' LS EXT. I have a 25 gal tank. For those of you that may have forgotten, most of today's trucks come with an owners manual. It'll tell you silly lil things like your tank size. :crackup:Hi, I happen to have a 2003 Trailblazer LT EXT and I just put in 20 gallons and the low light was not on, nor was I but barely under the quater tank mark. Is it possible that I have a 25 gallon tank?
