Fuel filters are a must on any fuel system. Keep your carburetor or fuel injection system flowing freely. Most inline fuel filters have replaceable fuel filter elements. You should inspect and change your fuel filter element regularly. You can't build horsepower with fuel flow interrupted. JEGS carries a number of fuel filters for most applications from Aeromotive, Fuelab, Earl's, Fram, Holley, MagnaFuel, Russell and more!
