ABSTRACT:
An apparatus for reducing or eliminating the occurrence of vapor lock in two-cycle engines isolates the fuel pump from the heat radiating engine block in a two-cycle, air cooled engine spaces the fuel pump from the carburetor and injects the fuel directly against the carburetor inlet valve. Application of an additional cooling means including airflow and liquid fuel means, may be provided in order to convey heat away from the fuel pump and therefore maintain the fuel pump temperature below the point at which vaporation pressure exceeds the impulse pressure generated from the power head. The fuel pump is removed from the hot carburetor as part of the vapor lock prevention system.
