Detailed Product Description

The Wix 33603 fuel filter is specifically engineered for use in a range of Volvo vehicles, ensuring compatibility and reliable performance. Its cellulose media material captures particles as small as 4 microns, preventing contaminants from reaching the engine and fuel injectors. The outside-in flow direction enhances filtration efficiency by forcing fuel through the filter media from the outside toward the center. With a burst pressure of 145 psi, this filter maintains structural integrity under typical operating conditions. The 5/16 inch inlet and outlet fittings match standard fuel lines, simplifying replacement. The filter’s dimensions—8.250 inches in height and outer diameters of 3.365 inches (top) and 3.170 inches (bottom)—are designed to fit securely within the fuel system of compatible Volvo models.
