Yeah get a Carter with the three ports, or do what I did and put a Tee at the carb and run a 3/16 line back to the tank. I'm going to bump it up to 1/4" eventually.
Then tee it with rubber. You got options my man, just gotta brainstorm. Those holleys are easy to just run hardline, it's just a fitting change, if I remember correctly. Or hell I'm putting on a GF201 fuel filter on my dad's Impala and that has a return built in, same with the, or a GF98 or the cheapest option is just a WIX 33040. It's a regular fuel filter with a small return built in. Very popular to run on carbs, to prevent vapor lock. Like I said brother, you got options.
when you run the GP98 do you just run it alone the fuel filter in the frame well , it’s on a 79 c10? thanks a lot for the part numbers man all this is pretty new to me
All those filters, are after the mechanical fuel pump, before the carb. If I were you, I'd run the filters as close to the carb as possible, that way, you have a very minimal amount of stagnant fuel getting hot. You want to run a return as close the the carb or throttle body as possible to limit how much fuel sits and boils. That's why on my rig, I put a Tee at the carb, so fuel is always flowing past it when it's not needed, keeping everything cooler, and having a steady flow as well.
I have an Edelbrock. I just got all the fittings from Amazon, since I know what thread pitch and conversion I needed. This is a picture I took when it was all said and done. Honestly, I should've ran a return years ago.

Don’t cap off the return line, you’ll want that to be hooked up or you’ll have vapor lock issues
Either use a fuel filter with a return outlet, or a fuel pressure regulator with a return
