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).

Use rubber lines that fit your fittings.
7.5 and 9.5mm.

They have to mate to the lines in the tunnel.

Bruce, yes, the return line from the tank will mate with the line in the tunnel. Sounds like you're suggesting a 7.5 mm rubber line there (instead of the 7 x 3 rubber hose that was there originally). Ok.

However, the send line does not mate with the tunnel line - it goes to the square fuel filter (8 mm inlet). Sorry I did not mention that in my original post. Thus, trying to figure out what line to use that goes from the 10mm tank pipe to the 8mm filter inlet.



As stated in original post the original rubber line there was a 5/16" (7.9 mm). I guess was the PO's solution - it appears to have worked since it's in between the two sizes it mates to on each end. Should I just try to find a new 7.9 mm hose?

For what it's worth ... the filter outlet goes to a 12 mm line which connects to the fuel pump. I'm using the square filter that came in Auto Atlanta's kit and a new fuel pump I bought from AA as well. The outlet from the fuel pump mates to the line in the tunnel.
