EDELBROCK 3604 Edelbrock 3604 E-Street EFI Fuel Line Return Kit for 5/16-Inch Fuel Line

The Edelbrock 3604 E-Street EFI Fuel Line Return Kit is designed for fuel-injected applications using a return-style fuel system. This kit supports the fuel circulation requirements of an E-Street EFI setup by providing the fittings and components needed to route fuel back from the pressure regulator toward the fuel system. It is intended for use with a 5/16-inch fuel line and is a practical choice for completing a compatible Edelbrock fuel delivery installation.
The kit is designed to work with a fuel pump and pressure regulator in a return-style configuration, helping create an organized fuel path for EFI applications. Proper fuel return routing can support consistent system operation by allowing excess fuel to be directed back through the return circuit rather than remaining at the regulator. The included fittings help simplify installation when paired with compatible fuel system components and line types.
Edelbrock brings established aftermarket fuel system experience to the E-Street EFI product line, and part number 3604 is built for enthusiasts and installers who need a dedicated return-line solution. Verify fuel line size, regulator compatibility, connection type, and vehicle application before installation. Professional installation is recommended when working with pressurized fuel systems, and all connections should be checked carefully for secure fitment and leaks before operating the vehicle. The kit is not classified as air restricted or truck freight only, making it suitable for standard product handling and shipping requirements.
