This is the 5/16" fuel line to frame clip that is used on 1954-1963 Pick Up Truck, Station Wagon, Sedan Delivery and FC 170 models with the L head 6-226 Super Hurricane engine. The clip is snapped into a 1/4" hole in the frame and the line then snaps into a groove on the clamp.

Multiple clamps are used to hold the line from the tank to the fuel pump and are as needed.
