Upgrading a 1965 Mustang to Electronic Fuel Injection (EFI) telegra.ph

The benefits of converting from a carburetor to EFI are substantial and immediate. Electronic fuel injection eliminates the cold-blooded behavior of carburetors—no more pumping the gas pedal or coaxing a reluctant engine to life on chilly mornings . Modern EFI systems are self-tuning, adapting in real-time to altitude changes, temperature fluctuations, and driving conditions without any intervention from the driver . This means your Mustang will run as perfectly at a mountain cruise as it does in your driveway.

Fuel injection also delivers improved throttle response, better fuel economy, and increased reliability by eliminating vapor lock and float bowl issues common with carburetors . The system precisely meters fuel based on sensor inputs—throttle position, manifold vacuum, coolant temperature, and oxygen content—ensuring optimal combustion under all conditions . For a car meant to be driven and enjoyed, not endlessly tinkered with, EFI is a revelation.
