you would have to get a fuel rail without a return line, or you would have to rewire you whole entire fuel to accept a return line. The 94-98 fuel systems have a return line, and the 99+'s don't. if you did this swap to add are return system to your car, you would have to get a 94-98 fuel tank and pump, run new fuel lines from the tank to the engine to add the return, and get a 96 computer. You would probably have to change alot of the sensors also, unless the engine came complete with everything.
