My 5.3 is 2008 Gen IV so it's a returnless system. As suggested above I used a Corvette filter regulator #LS9904. You mount it near the tank and it has an in port, an out port and a return port for your return line back to the tank. The Corvette filter regulator is used by many. It was recommended to me to use an oem one as many aftermarket can be unreliable.

05 Tahoe 5.3 direct from Chevrolet parts catalogue by vin# fuel line assembly has two lines one is pressure and the other is purge valve line. There is no third line for return
