    FiTech 36203 Details

    FiTech has realized that not everyone needs the biggest, baddest, highest-flowing fuel injection system you can get your hands on. Some of us just want a little more throttle response, be able to squeeze out better mileage and to make this change as easy as possible.

    The FiTech Go Street EFI Series is the answer you have been looking for when it comes to performance, ease of setup, and reliability. As ready-to-run as they come but still providing the best in performance and economy, the all-new FiTech Go Street EFI Series allows you to toss out that old leaky carburetor and bring new life to your favorite hotrod in the garage. This kit is designed for a simple, yet effective conversion to modern fuel injection technology at an incredibly affordable price.

    When it comes to converting to EFI, it’s important for the fuel pump to be installed in a cool area and what better place than in the gas tank itself. The pump is cooled by the fuel, it’s quieter plus there’s no chance of fuel starvation. To help ease the installation of an in-tank pump, this kit includes a new In-Tank Module assembly.

    This universal billet assembly can be used on tanks with a depth of 6” to 15”. The billet aluminum was designed with the supply and return ports in a parallel position to help route the fuel lines easily and evenly. The vent port is on the other side to ease routing the line near the fill tube. The two fuel ports are threaded to accept -6 AN O-ring boss fittings for a secure, leak-free connection.

    The cut-to-fit bracket secures a 340 LPH pump capable of providing fuel to 600 horsepower engines. To ensure clean fuel is pulled into the pump, two sizes of sock/filters are provided, a standard 11 square-inch design as well as a large, 35 square-inch version.
