When did Chevy vans get fuel injection?
Chevrolet introduced fuel injection on its full-size van models in the late 1980s, marking a significant technological advancement for the brand's commercial vehicle lineup. This transition from carburetors to fuel injection improved the vans' engine performance, fuel efficiency, and emissions control.
The Shift to Fuel Injection
Prior to the late 1980s, Chevrolet's full-size vans, such as the Chevy G10 and G20, were equipped with carbureted engines. Carburetors were the predominant fuel delivery system in most vehicles at the time, but they had limitations in terms of precise fuel metering and emissions control.
In the late 1980s, Chevrolet began transitioning its van models to fuel-injected engines. Fuel injection offered several advantages over carburetors, including improved fuel efficiency, better engine performance, and more precise control over emissions.
The Chevy G-Series Vans with Fuel Injection
The first Chevrolet full-size vans to feature fuel injection were the G10 and G20 models introduced in the 1988 model year. These vans were powered by a 4.3-liter V6 engine with throttle-body fuel injection, which replaced the previous carbureted version.
In subsequent years, Chevrolet continued to expand the use of fuel injection across its van lineup. The larger G30 model also received fuel-injected engines, further improving the performance and efficiency of the Chevy full-size van series.
The Benefits of Fuel Injection
- Improved fuel efficiency: Fuel injection allows for more precise control over the fuel-air mixture, leading to better fuel economy compared to carburetors.
- Enhanced engine performance: Fuel-injected engines typically deliver more power and torque, improving the vans' acceleration and towing capabilities.
- Reduced emissions: Fuel injection, combined with modern engine management systems, helps to lower the vans' emissions of harmful pollutants, making them more environmentally friendly.
- Easier maintenance: Fuel-injected engines generally require less maintenance and are less prone to issues like carburetor icing or tuning problems.
The transition to fuel injection was a significant milestone in the evolution of Chevrolet's full-size van lineup, marking a shift towards more advanced and efficient engine technology.
What is the difference between g10 and g20 vans?

What's the difference between a TBI 350 and a Vortec 350?
The differences between them are that the TBI had the injectors right in front of the throttle plate, where the Vortec placed the injectors behind the throttle plate; and the TBI was a speed density system, whereas the Vortec used a mass airflow system to manage the fuel-injection system.
