TSX 769 carburetor

[cpk]

Does anyone have information as to which Ford tractors were equipped with a TSX 769 large bowl carburetor? Here’s my problem. I know the TSX 813
came on the 801 series, so the 769 will fit. There’s a difference between the the two carburetors. TSX 813 has 7/16 threads where the fuel sediment
bowl is attached and takes the larger fuel line, 5/16 inch I believe. The 769 has the 3/8 threads and takes the smaller line 1/4 inch. I can’t find
information on where the break was on the different carburetors. I buy, rebuild, and sell Ford tractor carburetors, and need to know this information.
Any information or advice is greatly appreciated.
Thanks
Chris

I had made the notes below on this when I was redoing my Ford tractor 4040. I think it came via the ford tractor dealer I was getting parts from at the time, but I'm not 100% sure. I was having trouble finding a TSX769, they said a TSX813 would work. It is my understanding that these carburetors(TSX769/813) came on the 172 CI gas engines. So it would include the following Series 801,901,1801 and 4000. But it would depend more upon the Serial number, rather than the series as to which of the carburetors came on the tractor originally.


TSX-769 Before s/n 126524 1958 to 1960 172 ci ford part #312955
TSX-813 After s/n 126523 1962-1964 ford part #CONN9510C

Thank you very much for the information!
I believe I had my wires crossed a little. Even though the carburetors had different size sediment bowl mounting bolts, the fuel line diameter remained 1/4 inch diameter on both the tsx 769 and tsx 813.
The information you supplied is a very big help. And I appreciate you clearing this up for me!
Thanks again!
