ls fuel systems for idiots (me)

[texastrendz]

this is my first ls motor and i am having a hard time with the fuel system. i need help with the connections at the motor. i have a 04 5.3 liter vortec motor that is dbw. it has two fuel connections at the intake, feed and return i am assuming. how do i hook up the system with the corvette style filter/regulator combo? do i need the corvette style regulator? i assume that some of the 5.3 had regulators in the rails. any and all help would be greatly appreciatted, thanks daniel.
