FI-TECH Throttle Bodies 40003 Editorial Review
The FiTech 40003 Fuel Command Center is a fuel system supply unit designed to work with the FiTech injection system. It takes in fuel from the fuel pump at low pressure and builds it up to 58PSI, providing fuel to the Fitech throttle body. The product is intended to be easy to install and improve the performance of the engine. Customer reviews of the FiTech 40003 Fuel Command Center are mixed. Some customers had positive experiences, stating that the product worked as advertised and fit back in place of their old command center. These customers also mentioned that delivery was fast and the installation was easy. However, there were several customers who had negative experiences with this product. One customer reported that the command center stopped working before reaching 1500 miles, and when they contacted FiTech for support, they were told that this was not their product and that it was actually manufactured by Hyper Fuel. Another customer mentioned that the command center had inherent design flaws and a lack of quality control, causing problems and leading to a complete nightmare for their project. Additionally, another customer mentioned that the unit pushed a lot of liquid fuel out the vent line, requiring them to run the vent line back to the gas tank, which defeated the purpose of buying this kit. They also noted that the unit ran very hot and eventually replaced it with an intank system to avoid further issues. Overall, the FiTech 40003 Fuel Command Center has received mixed reviews from customers. While some users had positive experiences and found the product to be effective, others encountered problems with its functionality, design, and customer service.
