Sure thing! I know the struggle from having started with zero knowledge about how to work on cars myself, didn't have a dad or uncle or someone to show me the ropes. In fact probably the majority of what I learned about how to work on Mopars I learned from this site (been on here a decade now, has it really been that long? lol). And from screwing things up on my own lol.
Regarding the return line I think you'd want to make as much of it steel hard line as possible, that will have no issues with pressure and then for any rubber hoses connecting things together use the stuff that's rated for fuel injection systems. I haven't done it myself (yet) but that's how I would do it. I already have a fuel filter with the 1/4" vapor return nipple I just have it capped off for now (currently running a Street Demon carb). I have a wideband O2 sensor and AFR gauge in my car and I have noticed the AFR change when things heat up under the hood, exactly like I saw in Thunderhead289's video when he removed his FPR and closed his return line to temporarily turn it into a dead-head system. It runs fine as is but it'll probably run better with at least a vapor return and a pressure regulator.
Another issue is venting the tank once you install a return line. On newer cars there is simply a vent line going from the tank to the charcoal canister, I'm not exactly sure how to do that without a charcoal canister or some type of reservoir to safely "trap" the vapors. You could let it just vent out the gas cap but that's not ideal and kind of dangerous.
