ABSTRACT:
A fuel system is provided for supplying a second fuel different from a first supplied fuel substantially simultaneously to a plurality of injectors. In one form, an inner tube within an outer housing has a plurality of openings spaced from inlets to the fuel injectors for supplying the second fuel substantially simultaneously to each of the injectors, the number of outlets being less than the number of inlets. In a second form, the inner tube within the housing has a plurality of differently sized orifices increasing in size with increasing distance relative to the fuel inlet to the inner tube for supplying fuel substantially simultaneously to fuel injectors in registration with the orifices. In a further form, multiple inner tubes are used. In a fourth form, the main fuel supply line is divided and sub-divided through a series of T's or Y's to generate one fuel passage of equal length for each injector whereby upon changeover from the first fuel to the second fuel different from the first fuel, the second fuel is supplied substantially simultaneously to all injectors.
