66 BB fuel pump part number and picture?

Re: 66 BB fuel pump part number and picture?

Until the commercial interest presents itself, as it has in the case of dated wires, the supply chain for restoration parts will stick to providing the correct part number.

Should judging - the technical world - ever encounter the true meaning behind these codes, thus creating a technical demand, commercial opportunity will follow.

David, don't take offense, I do not believe the answer is there just yet.
How to break this code is to get at least 10 known original cars by model/part per month and then get this over the years of interest.

VIN-Build date-Motor=427-Motor Date-pump code

You'll need to do this for each motor configuration

Get the data and then run some simple datamining.

If you have that kind of data and are willing to share in this effort and others are as well the code can be clarified.

The motor build date tells you squat. The fuel pumps were installed at St Louis -- after, sometimes long after, the engine was assembled. You want to track the type of engine (suffix code would work, but so would size and HP) and the cars assembly date. In the case of C3s the trim tag build date would be adequate.

Tracking using the engine assembly date adds an additional time variable that can only add to the confusion.

Ron,

I have absolutely no interest in the NCRS judging world. I just want to know what the code on the fuel pumps actually means and after many years of research I believe that I may have unlocked this code. I probably know of only about a half dozen vintage cars with the original AC fuel pumps that fit my date code theory. I'm sure most fuel pumps were changed with 5 or so years and getting additional evidence will be very difficult. I also realize that I need more evidence to convince those who do not want AC fuel pumps to have a date code because finding NOS AC fuel pumps with the proper date code to match up with a vintage car will be almost impossible. It is more important to get a high grade from the NCRS judges or just know that the parts on your car are 100% correct?
I do not play in the NCRS judging world. I aspire to someting much better.

I must have been lucky. The car was 20+ years old and about 55K miles before the original fuel pump started to leak. It still worked fine, but fuel leaks are scary.

Edit add: While I am thinking of it. PRODUCTION 1970 LT1 fuel pumps are different in configuration than 1971 and 1972 PRODUCTION fuel pumps. Delco and Chevrolet part number (and so I presume the stamped number also) stayed the same -- but the real good judges can tell. I wouldn't be surprised there are similar differences in PRODUCTION configuration for other applications. If you really want to raise the bar, you have a ways to go.
