Tricks for eliminating fuel boil

I'm liking that filter. Can I use the can vent line as a return like I've read some guys are doing? Electric fuel pump and EFI will be last resorts. But I'll do what I got to do. Next is carb isolator and insulating the fuel lines as best as possible. Just trying to keep it as factory looking as possible.

If you do you need to do something else for a vent What year is the car? and does it have the separator in the trunk or does the vent go straight to the fuel tank?
