Back in 1992, General Motors introduced a new type of fuel injection system known as "Central Port Injection" (CPI), which GM also refers to as "Central Multi-point Fuel Injection" (CMFI). The system was used on 4.3L V6 Vortec engines through 1995, and was redesigned in 1996 and renamed "Central Sequential Fuel Injection" (CSFI). The Replacement Spider Injector is a fuel injection system commonly found in domestic cars. It has a central pump and eight thin tubes connected to it, resembling the shape of a spider. Its working is similar to that of a fuel injector. The pressurized fuel is mixed with the air and pumped to all the cylinders through tubes.
