Pump to carb fuel line

Looking for some direction on buying a OEM style fuel line for my 1972 Demon 340, stock thermoquad. I came across some on ebay but they state AVS or 66-67. I installed a Holley electric pump many moons ago and just ran a rubber line. I'd like to get it back to an OEM connection if I can. I appreciate any and all direction or links.
Inline tube has them. I bought one in stainless. Mancini Racing also resells the inline tube product. With this setup, the fuel filter goes between the frame rail and pump inlet.

The two piece design with the filter above the intake was an older design. I think they changed filter location to prevent leaks/fire. I think 72 was the changeover year.

here you can see some of how it routes
