Fuel rail crossover hose

1. A fuel rail assembly for a fuel-injected spark-ignited internal combustion engine comprising:

first and second fuel rails, each said fuel rail formed by a tube having a plurality of injector outlets, said first and second fuel rails comprising a first set of orifice outlets located at respective first ends of said rails and a second set of orifice outlets located at respective second ends of said fuel rails opposite said first ends, and one of said first and second fuel rails comprising a fuel inlet different from and located away from said first and second sets of orifice outlets, said fuel inlet being located intermediate said first and second ends of said one rail, said fuel inlet configured for receiving pressurized fuel directly from a low pressure fuel pump wherein said fuel has a pressure less than about 60 psi;

first and second crossover conduits for communicating fuel between said fuel rails, said first crossover conduit located between said first set of orifice outlets of said first and second fuel rails, and said second crossover conduit located between said second set of orifice outlets opposite said first crossover conduit; and

one of said first and second crossover conduits having at least one fluid flow restrictor at one of said crossover conduit connections for damping pressure pulsations within said rails and to balance flow therebetween and the other one of said first and second crossover conduits having an absence of said fluid flow restrictor.

2. A fuel rail assembly as described in claim 1 wherein said fuel rails are parallel spaced from one another.

3. A fuel rail assembly as described in claim 1 wherein each of said first and second fuel rails has at least two separate orifices to allow for fluid communication of fuel between said fuel rails and wherein said first and second crossover conduits are connected to said first and second fuel rails at opposite ends of said fuel rails.

4. A fuel rail assembly as described in claim 1 wherein said first and second crossover conduits are non-symmetric with one another.

5. A fuel assembly as described in claim 1 wherein connector fittings join said fuel rails with said first and second crossover conduits.

6. A fuel assembly as described in claim 5 wherein at least one of said connector fittings is connected with said at least one fluid flow restrictor.

7. A fuel assembly as described in claim 5 wherein said connector fittings are male barbed members and said crossover conduits are polymeric hoses.

8. A fuel assembly as described in claim 6 wherein said connector fittings are male barbed members and said crossover conduits are polymeric hoses.

9. A fuel assembly as described in claim 1 wherein one of said crossover conduits has a fluid flow restrictor at both end connections with said fuel rails.

10. A fuel rail assembly as described in claim 1 wherein said pressurized fuel is low pressure fuel on the order of 45–60 psi.
