Fuel feeding assembly

The assembly has a set of fuel feed bores (16), and common return passage linking all bores with a fuel reservoir. Fuel injectors (18) are mounted in the bores. Each injector has a return fuel port connected to an injector exterior. Each fuel feed unit has a feed passage supplying fuel to a relative injector. An outer surface of each unit and a wall of each bore form a return chamber connected with the common return passage. Each of the fuel feed bores intersect a corresponding injector bore.
