Anyone see a manufacturing date code pattern here? It seems like the B25 should mean "February 25", and the following A might mean first shift. What does the preceding 4 mean?...1974?

Re: What Kind Of Date Code Is This?...
Didn't realize OEM fuel pumps were date coded. Are you sure this isn't some foreign repo sub standard replacement part ID number?
Are you pulling a "John DeG" and playing "stump the tech board" again?

Re: What Kind Of Date Code Is This?...
Apparently, OEM fuel pumps ARE date coded...at least a recent thread seemed to show that. But, the stamp is so hard to see with the pumps installed on the engines that they are not judged, and nobody ever looks at them. I suppose judging is only by correct configuration, and the AC logo. Besides...I didn't say this was an OEM fuelpump...Didn't say what it was.
Me??!!...Stump the "Tech Board"??!! Nah...Not me...I spend too much time in the dark myself to be trying to stump anyone. Any help would be appreciated.Comment

Re: What Kind Of Date Code Is This?...
This is not the kind of dating that one finds on AC fuel pumps of the late 60's and early 70's. Generally they are bleived to be a Julian date, no year stamping--not a standard type date like shown in your photo.Comment

Re: What Kind Of Date Code Is This?...
agree with mike. i've never seen a c-1 0r c-2 fuel pump i considered OEM( production or service) that had a date stamped on the pump. mikeComment

Re: What Kind Of Date Code Is This?...
Forget OEM, C1, C2, C3... What I'm asking, "Is it a date code"? From what I know about Corvette date coding, I can read the dates on my Toyotas, but this one is a little strange.
And, THEN...on the same part, THIS! Is this the date code? I would read this as July 14, 1970. This part did come off a 70 Corvette...I'm just trying to figure out what/when/where/who etc.

That is simply a mold number--check any WCFB or AFB--tops, bowls, etc. have these numbers. NOT a date code!@Comment

Re: What Kind Of Date Code Is This?...
Chuck, With you new pic it's easy to see that the date code is 1970 195th day. Looks correct for your 1970 as far as date goes. Whew that was a hard one for the old timers. But we are not used to seeing date code on fuel pumps. But the boys do miss a lot of stuff on pumps as most just look for AC and 4 digit part number. Lot more to pumps than that. On the car it's so hard to judge pumps though without mirrors and telescopes. And with the time constraints put on the judges with so many cars to judge anymore you can't dwell on any certain item too long or CC will holler at ya. JohnComment

Thanks, John...
That's what I thought too. My car's build date is G30, or July 30, 1970. The pump's 195th day (July 14, 1970) would be close, but would precede the car's build date by more than a couple of weeks. The two weeks looks very reasonable to me, and it did come off my 70 coupe's base engine. I have the maintenance receipts on the car for about the first ten years of its life, and no fuel pump change was done.
BUT...There's just one little configuration problem that will keep it from being judged as the original fuel pump...Think this would cost me some judging points?

Re: What Kind Of Date Code Is This?...
Which?...The stamped number (4B25A)?...or, the cast in number (0-195).
I doubt the stamped number is a mold number...mold numbers are usually engraved into the mold itself such that the mold number is cast into the part surface. Stamping the mold number onto the part after casting would introduce un-necessary chance for error and is not typical in manufacturing.
Note the large 4 above the 0-195...that's most likely the mold number. Actually, the line above "Made In USA" is "0-1953"...I interpret the last digit, 3, as meaning 3rd shift.Comment
