Fuel Pressure Regulator?
Get the SFPH one that Rob mentions, I know it is correct. Besides being the return style LS1 regulator it also has to be able to regulate down to 38 psi at idle. Not all the adjustable LS1 units will. The first one I bought would only go down to 55 psi, which is the stock Vette fuel pressure. I know the one the South Florida carries works correctly.

HI!... I'm just running the billet FPR from AEROMOTIVE. It's a direct bolt on to the "97" to "98" 5.4 fuel rail that bolts onto all the 5.4 2-valve engines.

don't forget about the cost of the rails too...
imho, get the regulator from sfph or summit for a little more. if you replace the lines, go with some actual high flow lines, not the older model lines (i.e. 97-98).

HI!... I got my fuel rail with the bolt on non adjustable stock FPR from another engine I had so it was free. I bought the AEROMOTIVE billet FPR from SUMMIT RACING for about $110(U.S). AE1-13102
