It's perfect for any vehicle that came standard with a 2300 Holley Flange like some Fairlanes, Galaxies, Falcons, Comets, F100s, Javelins, Rebels, Mustangs, Thunderbirds, Cougars and more. It's economically priced so you can have all the benefits of EFI and still have money to finish or upgrade your ride! It also easily adapts to a square flange or Q-jet flange 4bbl intake with a Mr. Gasket adapter P/N 1933 (4150 Square Flange) or 1929MRG (Spread Bore).

These kits combine the Sniper EFI Self Learning Throttle Body, with an easy to install In-Tank Retrofit Return Fuel Module, 40 ft. of Earl's Vapor Guard Fuel Hose, and the required fittings. The included fuel system places a 340LPH fuel pump in the tank, which can easily be accomplished with basic hand tools.
