This fuel screen is a universal part that can be used in certain fuel sediment bulbs to keep trash and debris that accumulates at the bottom of the tank from coming in and playing havoc with the Carburetor. This screen slides on top of the sediment bulb inlet. The screen O.D. is .375", the pipe size is .216", and the length of the screen is 2.530".  
Note:  Some fuel bulb inlets can be drilled and this screen installed. A major part in keeping debris out of the fuel delivery system!
