Bought an intake complete assembly on ebay. Advertised as '03, has date code for '04. Noticed difference from my '01 ( no fuel press. regulator on fuel rail, no fuel return line) Would I be better to swap in my old fuel rails/regulator, or upgrade to later model fuel lines/regulator?? Fuel rail swap looks easy, but did not know if the other way would have some major benefit.

The Fuel Systems Are A Non Return Style System On The Newer Trucks. Yours Is A Return Style. Use Ur Old Rails For The New Intake....
