Universal Return-Style EFI Fuel System Kit

This comprehensive kit includes a fuel pressure regulator with an adjustable range of 20-120 PSI, along with durable fuel lines constructed from either CPE or PTFE materials. The CPE fuel hose is suitable for various applications like transmission oil cooler lines and fuel return lines, while the PTFE hose is ideal for fuel injection, boost lines, and LS swaps, offering compatibility with all automotive fuels and coolants. The fuel pressure regulator itself works with gasoline, E85, and alcohol/ethanol fuels. When installing, it is recommended to use thread sealant tape on the NPT pressure gauge port for a secure fit. Important considerations for this kit include its compatibility with gasoline, E85, and alcohol/ethanol fuels; it is not compatible with diesel fuel. Additionally, the Nylon braided fuel line option is not compatible with E85. The pressure regulator can operate up to 75psi, and for higher pressures, the internal spring will need to be replaced. EVIL ENERGY offers a 1-year warranty on this kit and advises users to measure their specific application before purchasing, as the kit does not include fuel rails. Installation involves standard procedures such as cooling the engine, relieving fuel system pressure, and carefully disconnecting fuel lines and electrical connectors.
