Default 3.4L to LS1 Swap - Fuel question

I have the donor LS1 car, but to save alot of time I need to figure out my fuel system. I have searched and tried to contact the members on here that have done the swap with no response. Basically I am putting a better fuel pump in, but am having a very hard time tracking down a decent priced corvette rail to keep my two line feed and return setup. Is there another option and what all would I need, so that hopefully I wouldn't have to really mess with my current fuel lines. Any help would be greatly appreciated.

You should be able to swap in a Walbro 255 pump.. I would keep the single fuel rail and run a Corvette FPR and that way you return line will be short and not have to run front to back. You can then strip out the return line.

The FPR, I have seen people either use the rail, or seen some that look like a fuel filter. What year corvette fuel filter is it that everyone uses, that gets dual in single out to the rail? What did you do about the EVAP system.

Thanks for your help.

The one that looks like a filter is a 99+ Corvette Fuel Pressure Regulator and Filter in one unit.

I has a inlet (3/8") and return (5/16") on one side and the outlet to the fuel rail on the other side (3/8")
