1.8L 1975 Connector between fuel line and tank, Mechanical Question about Rebuilding Fuel System Options

[briantrex]

Hi, I had a 1970 1.7L in 1986. Now, I've got a 1975 1.8L in 2018. I'm coming back to some roots and building a machine for my little guy to learn on. I'm rebuilding the front end fuel system--new fuel pump, filter, gaskets, and lines. I have taken everything apart. I have a lot of it back together again. I thought I had documented everything but I missed one bit. The two obtuse elbowed connections to the gas tank are different from each other. One, which I call "A", is shorter and has a tapered tip. The other, which I call "B", is longer and does not taper. They are the same diameter of bent short brass tube with a brass connecting nut on each.

I have two questions about these connections:
#1) Which of these connectors should be in line with the fuel pump and which in line to connect back at the firewall?
#2) Which of these connectors goes in which threaded hole in the fuel tank?

I'm thinking that the tapered end "A" goes in line with the direction of fuel flow but I don't know which one goes in which hole on the tank.

Help a new/old owner out? BTRex
