OK we all now know there are correct and incorrect seals,but the question that has not been answered is what is the correct diameter of the seal in question. there has been all of this discussion but no one is getting us to the nitty gritty of it all. the step by step assembly is great but not quite there! a picture of the seal in question would be great! It seems to be one of those it is right over there answers! where the xxxx is right over there? :?

I took a NOS fuel pump apart and measured both discs. The fuel side disc is 2 3/8 inches in diameter. The vacuum side disc is 2 7/8 inches in diameter.
