    FiTech 93508 Details

    The retrofit fuel injection revolution has begun! FiTech is the leading name in EFI conversions for good reason, bringing not only economy to the market but simplicity through design. The switch to fuel injection has never been easier. FiTech’s technology is designed and developed using OEM level engineering and components. All throttle bodies have built-in computers and sensors, reducing the amount of wiring to route in your vehicle. You can run the system on only 4 wires and two sensors! The sensors are OEM style for proven reliability and easy replacement.

    Mean Street EFI System Master Kit

    Put an end to mysterious air/fuel ratios, jet changes, and cold-start rough idle troubles with Holley Sniper EFI. Affordable aftermarket fuel injection is here and it couldn't be any easier to install on your vehicle. Holley Sniper EFI is a perfect match for any muscle car, classic truck, street rod, or nearly any other carbureted vehicle. Economically priced to save your hard earned money for other parts of your build; Holley Sniper EFI is a self-tuning, plug and play fuel injection system that takes all the trouble and guesswork out of your switch to modern electronic fuel injection. With over 100 years of building quality fuel systems, you can trust Holley Sniper with all your electronic fuel injection needs!

    Holley Sniper EFI is packed with all the features that your car or truck needs. This throttle body fuel injection replaces any square bore or spread bore style 4-barrel carburetor.

The self-learning ECU takes care of setting the baseline tune while the full touchscreen display allows you to fine tune as you please. Sniper EFI throttle bodies utilize OEM style TPS and IAC modules for dependable and serviceable use.

    FiTech Go-Spark CD Ignition

    FiTech EFI is excited to extend its ignition offerings with the new Go-Spark CD Ignition! The all-new Capacitive Discharge Ignition will deliver high powered sparks from idle to top rpm to improve the combustion event and power output of your engine.

    The Go-Spark CDI was designed for both EFI equipped or carbureted engines and features a microprocessor to manage the spark delivery. The ignition, which is assembled in the USA, produces a series of multiple sparks below 2,500 rpm to improve starting, idle quality and throttle response. At higher rpm, the CD technology continues to deliver full energy sparks through racing rpm to ensure complete combustion of the fuel mixture. 

    The Go-Spark CDI is designed for 4, 6, and 8-cylinder engines equipped with a distributor. It accepts the trigger signal from an HEI, amplifier, points, or 2-wire non-magnetic pickup distributors. The tach output signal, which is also used to trigger a FiTech EFI system, is a 12-volt square wave signal that is divorced from other circuits to provide a clean, perfect signal.

    FiTech Force Fuel System

    The all-new FiTech Force Fuel System makes the upgrade to fuel injection even easier! The Force Fuel simply connects to a stock mechanical or electric fuel pump then supplies the EFI system with high pressure through the use of an internal 340-LPH pump. This means you don’t need to run a new feed line from the tank!

    With a strong, versatile mounting bracket, the Force Fuel System mounts under and is fed with the original fuel pump. The assembly holds half-a-gallon of fuel to submerge the electric fuel pump to keep it cool for long life and no chance of fuel starvation. An internal regulator keeps the pressure at a consistent 58-psi which is ideal for reliable EFI performance.

    A serviceable 10-micron fuel filter is supplied to keep the finest debris away from the injectors along with five feet of high-pressure fuel hose, AN fittings, and clamps. The precision machined extrusion is designed for strength and sealed tight. There is also an easy-to-view fuel pressure gauge installed for quick checks and heavy-duty wire terminals are also supplied to complete the installation.

    • Designed specifically to fuel FiTech EFI systems as well as other brands
    • Capable of supporting the fuel demands of an 800-hp engine on gasoline
    • Sturdy, versatile mounting bracket provides a side or bottom mount
    • Effective 10-micron serviceable filter ensures the best filtration available
    • Uses a 340 LPH fuel pump and internal regulator for reliable fuel supply
    • Increased fuel capacity over other systems – no chance of cavitation
    • Supplied with high-pressure fuel hose, AN fittings, return line fitting bung, and liquid-filled gauge
    • For use with E-85, alcohol or methanol based fuels
