Abstract
A dual fuel connector separately supplies two different fuels to fluidly isolated fuel passages within a fuel injection valve of an internal combustion engine. The dual fuel connector comprises a body with separate fluid connections to the first fuel inlet, the second fuel inlet, a first fuel rail and a second fuel rail. A first fuel passage within the body is in fluid communication with the first fuel rail and the first fuel inlet. A second fuel passage within the body is in fluid communication with the second fuel rail and the second fuel inlet, and wherein the first fuel passage is fluidly isolated from the second fuel passage. The dual fuel connector supplies two different fuels to a fuel injection valve, for engines that are not designed with a cylinder head that has internal bores that can serve as fuel rails.
