Clean fuel is important because there are small jets and passages in the carburetor and opening in a fuel injector. The fuel filter is responsible for keeping the smaller contaminants in the system out of the engine and other fuel delivery components. On carburetor engines these contaminants can cause clogging of orifices or jets and cause the vehicle to get too much or not enough fuel.; Cartridge Fuel Filter; Prevents clogging and fuel delivery problems in your fuel line; Changing the fuel filter can improve your engines emissions; High technology filtration Package Dimensions: 3.917 x 3.917 x 8.146 inches Package Weight: 0.783 lb Package Quantity: 1 Anti-Drain Back Valve: No Bypass Relief Valve: No Filter Material: Cellulose or Cellulose/Synthetic Blend Filter Media Material: Cellulose Filter Type: Cartridge Gasket Inside Diameter: No IN Gasket Material: No Height: 7.25 IN Height: 7.250 IN Inner Diameter Bottom: 1.296 Inside Diameter Top: 0.625 IN Inside Thread Diameter: 2.813 IN Internet Product Code (IPC): 1F477B60751 Item Grade: Standard Replacement Item has MSDS (SDS)?: N MFG Brand Name: FRAM MFG Model # (Series): -00 MFG Name: FramGroup Non Slip Grip: No Outside Diameter: 3.938 IN Package Contents: Filter Smallest Filtered Particle (microns): 10 Supplier Company Name: FramGroup Torque Nut: No Width: 3.94 IN Country of Origin: MX Remanufactured Part: N
