Your classic car represents freedom and the joy of driving something special. But dealing with a temperamental carburetor can steal that joy, leaving you uncertain every time you turn the key. At Grease Diva Garage, we understand the frustration of hard starts, rough idling, poor fuel economy, and outdated fuel systems. That’s why we specialize in FiTech fuel injection conversions, transforming your classic car into a dependable vehicle without sacrificing its character.
Carburetors struggle with Colorado’s cold mornings, altitude changes, and hot summer days. Extended warm-up times, vapor lock, and inconsistent air-fuel mixtures are common issues. Adjusting carburetors or paying for repeated tuning often leads to temporary fixes. You deserve a solution that works consistently, regardless of temperature, altitude, or how long your car has been sitting.
FiTech EFI systems bring modern reliability to classic cars, using advanced sensors and computer controls to deliver precise fuel in every condition. These systems continuously monitor engine parameters and adjust fuel delivery hundreds of times per second, ensuring optimal performance whether you’re starting your car on a freezing February morning or cruising through the mountains on a hot July afternoon.
Key Benefits:
Imagine pulling up to a car show knowing your vehicle will start perfectly every time or planning a mountain drive without worrying about altitude changes. FiTech EFI combines vintage style with modern reliability, allowing you to maintain the classic appearance of your engine bay while enjoying thoroughly modern performance.
FiTech offers systems tailored to different needs. At Grease Diva Garage, we help you choose the right system for your vehicle and goals. The selection process involves understanding your current setup, performance expectations, budget considerations, and how you use your vehicle.
FiTech Systems We Install:
Each system includes all necessary components for installation. We explain every detail, ensuring you understand the benefits and costs. Our consultation process involves reviewing your specific vehicle, discussing your goals, and recommending the system that best fits your needs.
While FiTech systems are marketed as “easy bolt-on installations,” proper setup requires expertise. Fuel system upgrades, electrical assessments, sensor calibration, and comprehensive tuning are essential for optimal performance. Skipping steps can lead to poor results or new problems. At Grease Diva Garage, we’ve invested in specialized training and diagnostic tools to ensure every installation is done right.
FiTech systems typically require 58 PSI of fuel pressure, compared to the 5-7 PSI that carburetors use. This means your existing mechanical fuel pump won’t work, and you’ll need to install an electric fuel pump, often along with a new fuel pressure regulator, appropriate fuel lines, and sometimes even a return line to the tank. Electrical systems in classic cars also present challenges, as FiTech systems require clean, stable power to operate correctly.
Initial Consultation and Assessment:
We listen to your concerns, evaluate your vehicle, and identify issues that need addressing. This consultation involves understanding your complete experience with your vehicle, your goals for the conversion, and your budget. We inspect your current fuel system, evaluate your electrical system, and check for any existing mechanical issues.
Customized Installation Planning:
We recommend the best FiTech system for your needs, provide a transparent cost breakdown, and explain every step. Our planning process results in a detailed proposal outlining the recommended system, all necessary supporting components, the installation process, and expected timeline.
Expert Installation:
Our technicians handle fuel system upgrades, wiring, sensor placement, and integration with meticulous attention to detail. We install the new electric fuel pump, fuel lines, filters, and pressure regulators, followed by the FiTech throttle body and sensors. Wiring is routed carefully, ensuring reliable electrical connections.
System Tuning and Testing:
We perform startup procedures, road testing, and fine-tune settings for optimal performance. Road testing allows us to evaluate system performance under real-world conditions, ensuring the system responds appropriately in every situation.
Education and Support:
We explain how your system works, maintenance requirements, and what to do if issues arise. Before you leave our shop, we provide a thorough orientation to your new FiTech system, ensuring you feel confident operating and caring for it.
If your FiTech system isn’t performing as expected, we can help. Common issues include hard starting, rough idle, hesitation, fuel pressure irregularities, sensor failures, wiring problems, and software errors. We diagnose the root cause and provide solutions tailored to your budget.
Regular maintenance ensures reliable operation and peak efficiency. While FiTech systems require less maintenance than carburetors, they’re not maintenance-free. Periodic service keeps your system operating at its best and can prevent problems before they occur.

FiTech EFI (Electronic Fuel Injection) is a modern fuel delivery system that uses computer-controlled injectors and sensors to precisely meter fuel into your engine. Unlike carburetors that rely on mechanical vacuum and air flow to draw fuel, FiTech systems continuously monitor engine conditions and adjust fuel delivery hundreds of times per second for optimal performance. This results in more consistent fuel delivery, better cold starts, improved fuel economy, and automatic compensation for altitude and temperature changes.
Yes, FiTech systems are specifically designed to preserve the vintage aesthetic of classic cars while providing modern performance. The throttle bodies closely resemble traditional carburetors and bolt directly to your existing intake manifold in most applications. Most of the electronic components can be mounted discretely under the hood or in the trunk, maintaining the classic look while delivering modern reliability.
FiTech systems excel in Colorado’s challenging conditions because they automatically compensate for altitude and temperature changes through built-in sensors. The system continuously monitors barometric pressure, air temperature, and engine conditions to adjust fuel delivery accordingly. This eliminates the need for manual carburetor adjustments when driving from Denver to the mountains or dealing with seasonal temperature variations.
FiTech offers systems compatible with most popular classic car engines, including small block and big block Chevy, Ford, Mopar, and many others. However, successful installation depends on your specific engine configuration, intake manifold type, and existing fuel system. A professional assessment is recommended to determine the best FiTech system for your particular vehicle and ensure all supporting components are compatible.
Most FiTech installations require upgrading to a high-pressure electric fuel pump (58 PSI), installing appropriate fuel lines and filters, and adding a fuel pressure regulator. Your electrical system may need upgrades to provide clean, stable power to the EFI system. Depending on your current setup, you might also need a return fuel line to the tank and various sensors for optimal performance.
