A manifold for an engine, comprising:
- a body having an air/fuel passage through which fuel and air flow to the engine;
- and
- at least one of a fuel injector and a vapor separator carried by the body and through which liquid fuel is provided into the air/fuel passage.
An assembly to provide fuel to an engine, comprising:
- a body adapted to be coupled to an intake manifold, the body including an air/fuel passage through which air flows to the intake manifold;
- a fuel injector carried by the body and communicated with the air/fuel passage to provide fuel into the air/fuel passage;
- and
- a fuel/vapor separator carried by the body and including a volume of fuel that is communicated with the fuel injector.
