I know there has been discussion about the gas tanks in 1LE cars.

I am trying to confirm something. As I understand it, the gas tank that was part of the original 1989 1LE package became standard on all f-bodies in 1990.

The difference with the 1LE tank was simply an internal baffle which would hold fuel when the tank was low in a hard corner.

I recall some discussion about a swinging pickup, but that may have been an earlier design prior to the internal baffle.

Does anyone have real truths?

Mark.
PS. No need to get into the 15 vs 18 gallon tank debate.

Yeah, they had a swinging pickup, but never heard about the 1LE tank going into the rest of the cars. Has anyone done a swap?

i was reading about the standard baffling was in the 90 - 92 thirdgens, thats all i was really worried about.

my 88 when low of gas would choke almost in a hard turn, my 91 hasnt did anything like that yet.

I used to have 89 and 92 Camaros that would die when I took a hard turn with less that 1/4 tank of gas. My current 92 B4C\1LE is supposed to have the special tank with the baffles yet I experience the same fuel starvation in hard turns with less than 1/4 tank of gas. If the baffled tank is supposed to remedy this, it isn't working!

i have the same prob with my 91.

matter of fact, with the WEAK l03/2.73 open rear launch, i STILL need the needle between 1/4 and half tank to keep the pickup submerged.

Strange, that has never happend to me even when i was almost running on fumes. Usually when i fill with gasoline i need 50-56 liters and thats almost empty. Well i guess i might be lucky, but i have never heard of anyone else with that problem.

MrDude_1

how hard are you turning and braking?


it runs fine as long as i dont brake hard and turn or launch hard.


next time its low, try stopping as quickly as you can..... it'll stall.



well, as long as you have EFI it will..... carbed cars wont have this problem.....

I will try this when the snow is gone, so i get back on this subject in 6 months.

All I know on this subject is that the 90-92 gas tanks you buy aftermarket are the same part number as the previous ones, so they may be all baffled or all not baffled.

I had an 85 camaro 350 carbed, and in order to do dounts I had to have a full tank gas.

the 1LE tanks are also 18 gallons....

ive seen the inside of a "1LE' tank and the tank on my 91 GTA is the same...

it has a little plastic "box" that the fuel pump sits in...

dj's B4C

I disagree on the fuel capacity in the 1LE.

1. The owners manual has no reference to this fact.
2. So far I haven't put over 15 gals in my 92 1LE.

P.S. I still have the fuel starvation problem when cornering hard with less that 1/4 tank of fuel (baffle? I don't think so).

Love these cars!

I once ran my GTA down near empty. When I filled it up it took 19.5 gallons to sate the GTA's thirst.

And I have fuel starvation problems when its below half tank while in turns. So I don't think I have a 1le tank, just a really odd car.

Mark_ZZ3

Just curious ... is the 15 vs 18 gallon issue just an US gallon compared to an imperial gallon?

15 imperial gallons is approx 18 US gallons.

i also ran it dry and filled with 18.4 gallons...so either the tank is 18+ galllons or the gas stationS ive been going to for 3 years have been ripping people off...and i tend to think that they get caught "selling" 3 gallons when they didnt...3 gallons x 15 gallon tanks x 200 cars= no chance they get away with it

ive only "stumbled" my car one time..its had about a gallon or so and i did a 90 degree corner at 65 and it choked a little

its not the best idea to come here and basically call somone a liar..especially since ive opend up an 1LE tank aswell as the one in my 91 GTA...like i said and ill say till im blue in the face...there ARE baffles in the 1LE tank....now untill you opne up your tank and look for the baffles dont hink that u dont have them...
your FP pickup could be bent causing it not to sit on the bottom of the tank..

The new brake systems was well received by race teams, but this created a new problem. Given this tremendous new braking ability, the Camaro's tank mounted fuel-injection pump could be starved fuel and the engine stalled under hard braking. The solution was to completely redesign the fuel tank, installing baffles and a new pick-up/sock design to keep the pick-up submerged even when the fuel level dropped below a quarter of a tank. This was important because in the Canadian Players Challenge series the cars were not allowed fuel stops. Fuel management became critical during the 45 minutes of all-out racing. And, of course, the rules required that race cars use the original fuel tank/pump/pick-up. Sometime after 1990, the updated fuel tank systems was integrated into every Camaro sold.

i thought id save yall some time...

And another quote from Chevy Rumble ...

"One interesting race-bred improvement to eventually find its way to the production line for all third-generation Camaros was the baffled gas tank. When the tank was at about one-quarter and the race car came out of corners hard, the fuel pickup was starved and it bogged the car. The baffle solved that and all the tanks were fitted with them."

Wow! Now I'm calling people liars!
Thought that I was just stating my experiences!
If there are baffles in my Camaro (1LE) then I must be some hell of a driver cuz I can get the car to stumble (as I stated before) when under a 1/4 tank of gas.
Maybe I just drive harder (and better) then you can!

Love these cars!
Hi Willie!

sllt1776

my car does the same stumble. below 1/4 tank and especially on right turns....weird. i know my tank is not baffled but it's not a 1le either. someday i'll swap in a 4th gen tank.
