Claims17
A fuel rail assembly for an internal combustion V engine, said fuel rail assembly having a pair of side-by-side spaced apart fuel rail segments, each fuel rail segment including a section of tubing and a plurality of fuel injectors installed therein;
- a crossover hose connection between said fuel rail segments comprising a pair of end caps each inserted into one end of a respective fuel rail segment, each end cap comprising a hose barb fitting having one end slidably fit into a respective fuel rail end and another arm projecting out of said fuel rail end;
- a seal on said one end of each hose barb fitting sealing said one end to an interior wall of a respective fuel rail one end;
- retention means retaining each of said hose barb fittings in position with said one end thereof inserted in said respective fuel rail end;
- and,
- a crossover hose having each end fit to a respective fitting projecting end to establish a fluid tight connection between said fuel rail segments.
A method of constructing a crossover hose connection for a fuel rail assembly for an internal combustion V engine, said fuel rail assembly comprised of a pair of side-by-side spaced apart fuel rail segments, each formed by an elongated hollow tubular member receiving a series of fuel injectors at spaced locations along the length thereof, said method comprising the steps of:
- installing one end of a hose barb fitting in each adjacent end of said fuel rail segments to be sealed and retained there;
- and,
- fitting either end of a crossover hose to a respective projecting other end of each of said hose barb fittings to establish fluid communication between said fuel rail segments.
