    Not sure about the pros and cons of each. Whatever your engine has I would run. If it has a return, just use your original fuel line plumbing for the install. If it's returnless, just cap off your existing return line.

    Well I'm fairly certain my truck now has a return system and most of the intakes I have found has a return. So I guess I'll just go that route that way I don't have to change much in my fuel system.
