My car is a 03 z w/an 02 fuel sys---early 03...we ran out of fuel with stock line at 580 rwhp---383 stroker,,we installed a -6 return line and stock 97-98 fuel rails and adjustable regulator set at 60 lbs/ no vacuum which gave us a little more hp.Just change the fuel filter to a 97-98 and it is a direct fit for 97-98 rails. I now have to do a -8 or -10 feed to go with the -6 return to go above 725 hp--i am detuned now..it depends on how much power you are going to make..Been there done it and got a headache...

not in front of me but can have all part #'s this wednesday,,,you can email me at vetter345@aol.com and i can reply quicker..i am only on the forum every couple weeks....the fuel rails are factory 97-98, you can use adjustable regulator, but stock is better in my opinion..also get a 97-97 fuel filter, and aeromotive -6 line to connect to stock return pre-filter..you will run a new line from engine to old return line, main fuel feed remains stock...also how much power are you going to push because there is a limit to stock setup...Dave
