    Drop-In Retrofit EFI Fuel System

    Are you interested in an EFI retrofit kit, but just can't get past the complexity of the fuel system? Holley's Universal In-Tank Retrofit Fuel Modules are available in return and returnless versions to quickly and easily convert your factory tank or fuel cell to an in-tank EFI fuel system using only basic tools; no welding or metal fabrication is necessary. Each low-profile aluminum module includes a pump hanger bracket to control pump vibration along with an innovative clamping system that allows it to be positioned in the tank near the existing sending unit. Once installed, simply hook-up the fuel lines, power source, and ground; then you're ready to run!
