LS2 with LS6 manifold fuel system

[black67malibu]

since I have the LS6 manifold on my LS2 with what looks to be a FPR built into the stock fuel rail system. Does my fuel system still need to use the corvette fuel filter/pressure regulator in it? Also, does someone make a kit thats a little more cost effective than a SS line stylde? So far I found the fuel filter/pressure regulator at speedway for $69 and just need lines ect. I have a used Ricks hot rod shop tank. Thanks, Tyler
