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

Make sure you put them back in the correct holes on the bottom of the tank. Put the one with the bigger pipe into the screen in the tank. There is a riser in the tank that will limit your gas feed by about 3 gallons if you mix them up.

You can remove the screen to verify which one. Or just remove the filler neck and look inside. The suction is in the middle of a ring inside the tank.
