Return fuel line question

I’m trying to go from -6 am to the stock return line at the firewall which adapter do I need? The return line doesn’t have the efi push on like the feed line does.

There is no adapter fitting. IIRC the return line just has a barbed hose end. Why are you trying to make that short section of return line bigger? It's not going to change anything.

I’m installing a inline adjustable fuel pressure regulator and I just need to mate up to the stock return line at the firewall. I could use a different size line off of the fuel pressure regulator. What would you recommend
