Im not sure where to put this so i will ask here, How many gallons is my fuel tank in my 92 RS? thanks!

 

14-15 i think
i know i have been down to about 13 1/2 before

 

If I remember correctly, I was able to put in 15.2 once, but I was really running on fumes when I did that. Normally, I'll put in 14 or so, but our gas gauges suck, so who knows when your actually on E?

 

I ran it completley out of gas, put in 1 gallon from a portable can, then put in another 13 at the gas station.

maybe its different depending on the year?

 

maybe you were shaking your car side to side like a NASCAR driver trying to get evey last drop out of the tank?
lol

 

I was cruising home from Charleston to Atlanta like at 2 AM on a Sunday. There was nobody open, and I was in the middle of nowhere. Apparently the one I finally found off like "Bob's Road" was the only one within a 90 mile stretch. Damn car started to choke when I pulled off the exit and into the gas station.

 

i believe tis 15.3 gallons

 

I think GM has them officially listed as 15.5 gal.

 

azvolfan is correct, the owners manual says 15.5 gal.

 

Yes, with the previous two Posts 15.5 gals. Stock tank on all Camaros & Firebirds.

 

I still say our gas gauges suck.

 

Mine holds 16 plus a little when it's empty. The guage even has 0 to 16 gallons on it. Between 82 and 92 some different tanks were produced, some with baffles, some without, etc...

 

I agree.

 

ahhhhhhh come on I like going 200 miles on the first haft and 100 miles on the second

 

Fuel injected cars have a 15.5 gal capacity. Carbureted cars WITHOUT an intank pump have a 16.2 gal capacity.

The tanks themselves are all the same size.

 

man I get worried when I let it run down to the E and put in 11.5 gallons LOL Guess I don't have to worry so much now

 

Officially, they may hold 15.5. But that also doesn't mean tha tyou can always get it all out. The pickup doesn't come equally close to the bottom in all tanks.

 

General rule of thumb is that you can't burn the last gallon... These tanks seem to be the last half-gallon, probably because of their oddball shape.

 

16 gallons 'till 1986, then it went to 15.5 gallons. I think they added internal baffles to the tanks to keep fuel at the pump. (know my 85 doesn't have them)

 

Wrong. I can pull out my 1984 owners manual which shows 16.2 gallons for all engines except the TBI Iron Duke. That one was 15.5. Guess what it said in 1983? TBI 4 cyl and Crossfire were 15.5... all others were 16.2.

It has nothing to do with baffles or any other part other than the in tank fuel pump. The pump takes up approximately 0.7 gal. The baffles take up so little volume as to be negligable.

 

Wrong, to you. I can pull out my '85 camaro owners manual and it says 16 gallons.

 

It's too damn cold out to get my manual

 

Don't make me take pictures of my owners manual...


FYI, in case you're curious, my car used to hold 16 gallons. Now it only holds 15.5. I installed an in-tank electric pump. Same tank.

 

call it 15 gal, I know in mine once I get down to 3 or 4 gallons in the tank I start getting really bad fuel starvation even in mild corners

 

Funny, I don't have this problem. I heard tell one person said it had to do with some doohickey on top of the motor called a carbumorater which has some fancy part in it called a "float bowl".

 

hmmm I wonder where that float bowl thingy is on my TPI?

 

Well we BEAT THIS SUBJECT TO DEATH! So if you have to put 15.5
or 16.5 gals of fuel in your gas tank you waited to long and your out of gas the same way as this Topic. .:lala: :lala:

 

you installed a pump the size of a half gallon of milk??? What do you have under the hood? Does it say Pratt&Whitney?

 

Actually, I never really had this problem in my carbed car, but my friends car with 5.7 tpi did. I have known of a couple of tpi motors that did.

Ben

 

fuel starvation is well known problem in TPI's....gotta have that 43 psi of fuel, you carbed guys need what 6 psi?

 

The only time I see over 150 miles to the tank is when I forget to reset it.

 

same here, or when I am on a long trip.....around town my foot is just too heavy

if i see 150 one a tank i better be driving towards a sunoco station. i get 10 mpg.

 

I still say our gas gauges suck.

 

Just filled up last night and put 11.2 gallons in, the fuel gauge was reading on empty hehe. Plus there was this black mustang there with huge wire rims in the style of that one green mustang on Monster Garage. The guy had his hood open for some reason, slammed it down and his alarm went off lol

 

And I say that's a runner up for understatement of the year.

 

When my gas tank went bad, i bought an auto store replacement part for it and it somehow had an increased fuel capacity their computer said so and the box did too under capacity. I believe it holds 17 gallons. and yes it was a **** to install compared to the removal of the stock. The straps did not want to fit at all.

 

Hey does anyone know of a method to make the gas gauge more accurate? I mean, besides getting a new gauge and sending unit. How about the 4th gen tank swap... Ive been reading about that. Is the sender in that tank more accurate, hence making the gauge more accurate? Anyone know?

Justin

 

I doubt it. The sender in my Hawk is not terribly better than the NEW sender in my 84 Camaro. Both are quite a bit better than the original sender in the 84, though.

GM is too cheap to use a fancy sender to compensate for the odd shape of the gas tank, so there isn't much you can really do.

What steams me is the gauges are ALL controlled by the ECM on 99 and newer cars, and they couldn't be bothered to put a simple correction table in the hardware. I know they could have done it, too, because that's how they got the temperature gauge to read 210 exactly any time the temp is between 180 and 220...

 

Hmm I always thought that was a safety mechanism. I don't want to know how many people would be getting stranded cause they ran out of gas, cause when the gauge hit empty it was being acurate and actually meant it I think pretty much all cars even when they say empty still have about 3 gallons of usuable gas in the tank so you can get to the next gas station hopefully.
