Abstract

Abstract A fuel line receiver has a fuel passage terminating in an enlarged region. A retainer ring secures an O-ring in the enlarged region. The tip of a fuel line is curled to facilitate insertion through the retainer ring and the O-ring into the fuel passage. The O-ring sealingly engages the fuel line and the peripheral wall, and the tip of the fuel line is supported by the fuel passage and the retainer ring. A flange on the fuel line is engaged by a nut or a clip to hold the tip of the fuel line in the fuel passage.
