The Wix Filters 33482 is a complete in-line fuel filter engineered to provide OE-level fuel system protection. It is confirmed to fit the Chevrolet Corvette with the 5.7-liter V8 TBI engine for model years 1982 through 1984. This filter is used between the fuel tank/pump and carburetion/fuel injection system to trap particulate contaminants before they reach the engine.
Its filtration media is made of high-grade cellulose with a confirmed nominal rating of 13 microns, which balances flow and particle trap efficiency. The filter’s design includes both inlet and outlet ports that are 3/8 inch diameter, and a height of 5.546 inches (141 mm) with an outer diameter of 2.160 inches (55 mm) on both ends. The top inner diameter is closed according to confirmed specs.
Real-world benefits include improved engine longevity, prevention of fuel system component clogging (such as injectors or carburetors), and maintaining performance and drivability under standard usage. This filter is intended for gasoline applications with the specified Corvette engine; when replaced at recommended intervals, it helps avoid fuel delivery issues and maintains reliability in the original fuel system setup.
