How to Change a 2004 Z06 Corvette Fuel Filter
The main function of the fuel filter on the 2004 Z06 Corvette is to remove the sediments from the fuel before the fuel reaches the fuel injectors. The fuel is pumped out of the gas tank by the fuel pump, then circulates through the fuel lines and into the fuel filter. The sediments from the fuel are then trapped inside of the fibers on the fuel filter. The clean fuel then flows to the fuel injectors and the engine.
