The fuel rail only has one connection, where do I attach the return fuel line?
The LS1 fuel rail is a return-less design and requires a regulated fuel supply at a pressure of 58 psi. The fuel rail is configured for a quick connection fitting. Revision of the rail connection may be required for different style connections. The 1997 Corvette fuel rail incorporates a pressure regulator and can be substituted when using a fuel system with return line.
