ABSTRACT:
An improved fuel injection system includes the use of an additive supply which may be selectively injected into the combustion chamber of a vehicle's internal combustion engine through the use of a manually controlled, electrically operated pump. The pump is electrically operated by a switch positioned on the dashboard of the vehicle and serves to transfer the fuel additive from an additive tank to a carburetor or fuel injector system. Further, a bypass line is provided around the conventionally employed fuel filters positioned within the regular fuel line so that fuel may be selectively delivered to the combustion chamber in the event that a fuel filter becomes clogged.
