Just to add input, I looked at the tank I removed from my 07D '68'. Same location as the others and stamped 68  52. Hope this helps, RonM.

OK, what's CRG's input on the gas tank date code debate?  Are all of the original stamps only four digits?  What does CRG believe to be the correct way to decipher the code?    Huh

Well, let's compile the data. I dug out my tank and added it to the mix.

12D  68 20
02C  68 27
07D  68 52

01B  21 69
01C  22 69
05A  37 69
06A  24 69

I think the code is a running week date, starting at 01 about August and incrementing throughout the model year.
More data would help. Anyone with an early 68 or early 69 car (Aug-Dec) that can add their tank date?

Thanks Kurt!  I knew you would have a theory.

I did a quick search over at Team Camaro.  "Gary L" has an 02D '69 Z/28 with a gas tank date code of 29 69.  I've added his data* above.

Added mine from 68. The running week theory seems to work out so far. This thread has been interesting. I never knew it was stamped. Anyone else not checked in yet that can confirm thier origonal tank?

Found mine right where John Z. said, front corner, drivers side.
The date appears to be 2 4 69 with the 4 stamped upside down. Anyways the car is 06A build.

I was looking through the info again and there appears to be a discrepency with  '06A  24 69'

I think it would fall in line with the other dates we are seeing if you consider the 2 being upside down instead of the 4. Then it would read 69 42 and fit with the rest of the data. After all 69 is the same either way you look at it. Wink

That's my tank and I was wondering the same thing.

Here goes my first attempt at this forum.....  since you were looking for an early production '69 you made me go look (never checked before).

My 10A '69 Norwood Z/28 has a gas tank code of 6  69 (very clearly stamped).  The car has approximately 40k original miles and still has the original gas tank as far as I know...

Learn something new every day !!

Thanks for the info...

Thanks guys for the additional data!
Thanks Kurt!  I knew you would have a theory.
I didn't have one until I compiled the data. You forced me to come up with one. Smiley

I would agree the 06A tank either sat for a while or is misstamp.

Interesting. Since they had the year on the tank, they could just keep counting - higher than 52 wasn't a problem.

12D  68 20
02C  68 27
07D  68 52
07D  68 53

10A   6 69
01B  21 69
01C  22 69
02D  29 69
05A  37 69
06A  24 69

Here is the latest list with the 06A Flipped around assuming the 2 was upside down instead. Seems to make more sense. Funny how every once in awhile a digit on a part is reversed or upside down. I never realized how common these types of issues were until reading alot of these posts.

12D  68 20
02C  68 27
07D  68 52
07D  68 53

10A   6 69
01B  21 69
01C  22 69
02D  29 69
05A  37 69
06A  42 69

It was interesting to figure out. Not a lot of data, but it was Pex's 12D data was problematic and important - the wrong calendar year for a 12D car.
I tried day combinations, day week, ignoring the 12D data, etc. Took a while to break the normal dating paradigm to come up with something that made sense. Looking back, it's a duh, ....now.... Smiley
