Lower fuel line questions (under tank) Options

[DC_neun_vierzehn]

Looking for help regarding correct fuel lines while I await a new Dansk tank to replace the unusable one I received (thread here).

I have a '73 2.0. A PO moved the fuel pump up front and under the tank and cut out a door so that the fuel pump can be accessed from the frunk (like the '75 and '76).

First question: regarding the send and return pipes on the bottom of the tank - the send line measures at 10 mm and the return at 8 mm, yet the list in the AA fuel line kit lists both lines as 7 mm. Is that correct? I didn't want to force it, but I cannot seem to get the 7 mm line in the kit over that 10 mm pipe.

Here are pics of the pipes I'm speaking of as well as pics of what the lines were when I removed the old tank (a 5/16 AKA 7.9 mm USA made line on the send and a 7 x 3 made in Germany line on the return).

Do early tanks have two different size lines coming off of the tank?

The send/return lines on my '75 tank are the same 8mm (OD).
I would replace the 10mm fitting on your tank with an 8mm one.
What Chris9146 said is how it should be set up. On my fuel filter there is an arrow indicating fuel flow direction. If yours doesn't have that, then it probably doesn't matter which way you connect it.

I would also recommend Gates 3014 T2 fuel line. It's rated for ethanol and 225PSI, so safe for FI. Pricey, but better safe than sorry. I was able to buy it from my local NAPA store.
