Fuel Return Line

[Ponti-MANIac]

Do the 2000 LS1's have a fuel return line or are they returnless?

With a little research I answered my own question

EFI Fuel Rails

Corvettes, '99 and later, plus all Camaros LS1s, use a fuel delivery system that does not require a fuel tank return line. This system is very difficult to adapt in an engine-swap situation. Fortunately, earlier '97-'98 Corvettes employ the traditional feed-and-return-line fuel system. If you happen to have a non-return-line LS1, the fuel rails must be modified for a two-line system. Once again, Street & Performance can modify your existing fuel rails or provide you with the correct fuel rails.

well thats half right.....they have a return line but it doesn't run back from the fuel rail.It splits off after the fuel filter back to the intank fuel pressure regulator then dumps back into the tank.
