    Note: This kit is not carb approved for use on emission-controlled vehicles. It is not legal for use on pollution-controlled vehicles. This system is designed to control the EFI and ignition on LS-based engines being retrofit into older vehicles that do not require emission controls.Upgrading to electronic fuel injection is one of the best ways to improve the performance of your classic vehicle and FiTech is making the swap even easier with their new In-Tank Fuel Pump Module. The universal assembly allows you to easily mount the required high pressure fuel pump in the best location, the tank! The assembly secures the supplied high pressure pump in tanks with depths ranging from 6” – 15”. The fuel is pumped to a top billet mount assembly to -6 AN male fittings for the supply and return ports. The billet mount was designed with a low profile and places the ports in a parallel position to help when routing the fuel lines. The vent port is on the other side to ease routing the line near the fill tube. To ensure uninterrupted delivery of clean fuel, two sizes of sock/filters are provided, a standard 11 square-inch design and a large, 35 square-inch version. The Universal In-Tank Pump Module is supplied with everything you need for installation including a high output 440 LPH pump capable of supporting up to 1000 horsepower engines (normally aspirated). Push-lock style AN fittings are also included along with gaskets and wiring terminals. When it comes to upgrading to electronic fuel injection, setting up a proper high pressure fuel system is paramount to the overall performance of the vehicle.
