The Crossfire Throttle Body Injection was introduced on the 1982 Corvette as the new fuel delivery system. It can be described as a cross between a carburetor and fuel injection. The first-edition C4 corvette in 1984 continued to use this fuel delivery system. The fuel pump was located in the tank. The GM specifications for fuel pressure was 9 to 13 psi; however, the recommendation was increased to 14 psi to eliminate occasional stumbling or if the engine wasn't getting enough fuel at about 4,000 rpm.
