Abstract
A fuel increasing system for an internal combustion engine having a normal charge forming system with a plurality of carburetors. A supplemental fuel supplying system is incorporated that draws fuel from the fuel bowl of one of the carburetors to a supplemental fuel pump which, in turn, delivers fuel under pressure to a pressure regulating valve which regulates pressure by discharging excess fuel back to the fuel bowl from which it is drawn. The discharge of supplemental fuel to the engine is controlled by individual supplemental fuel control valves mounted on each of the carburetors.
