Can anyone tell me application for this fuel pump? Im coming up with 69 455? Aren't 70 w-30 fuel pumps unique looking?

 

Airtex 40736, will fit a lot of Olds setups (won't clear the AC on my 350) but I don't know what the original application was.

 

Definitely not 69. 68/69 had pipe thread for the outlet and used an adapter fitting to change over to the inverted flare. 1970 is when they started with the inverted flare, but I do not recall seeing the large can like that.
