Im new to the blazer world, i have a 01 4 dr . I was wondering what is the tank size that comes in these . I been having problems with the gauge so it seems. When its on Empty i fill up and only dump 13 gallons into it, and check the mileage and it says between 190-195....Cant be right .Anyone know anything ?
Thanks Jason

 

4drs have 18 gallon and 2drs have 19 gallon tanks.

 

Cool thanks...wonder why its only taking 13 gallon then...gotta be the sensor is fubar...

 

On mine when the gauge shows ~1/8 of a tank remaining, the gas pump only shows ~14 gallons going in to fill it up, so yours seems to be in the ballpark.

 

yeah I just bought my 99 4dr. on 11/27 and the first time i saw the gas light come one (even though it was because i stomped on the gas) I filled it up and squeezed in a little over 13 gallons. I managed 200 miles this time before it got below 1/8th and i am filling it today after work, i expect it to take a little over 14 gallons, but we'll see.

 

Seems that 13-14 gallons when the light comes on is common fill up then. I imagine that when its totally on the E then might be able to squeeze 16 gallons into her then. You get 200 out of a tank ? thats what im getting also...some tell me i should get 220-230 plus out of a tank...not sure how its going to get that kinda mileage..

 

well I got 201 out of 14.6 gallons this time, that's about 13.5 mpg, but we had snow, and a bad flood here so that's not too bad i suppose. it does seem that if you fill when you first see the gas light staying on, you get 13-14 into it...

 

I have one line under the 3/4 full mark and right now it has 52 miles on it...so that would or should be about 200 ish a tank then...hafta see i suppose when she gets down to E what the mileage is.

 

fuelk gages register differnetly. You'll have to watch it and see.

Mine likes to take forever to drop to 3/4 tank, drop quick to 1/4 tnak and then take it sweet time to empty, and even then I still have 3 gallons in the tank when my gas light comes on. Every one is diferent.

 

Its definetly a weird thing, and probly a chevy thing. This is the first chevy brand that i have own...quite possibly the last..lol
