Patent ID: 8069830

Claim:
A method of providing a primer for a marine engine with extremely low hydrocarbon permeation comprising: providing a rigid housing containing pump body, a continuously molded fuel flow path, an entrance check plunger at a first end of said fuel flow path and an exit check plunger on a second end of said fuel flow path, said check plungers preventing reverse fuel flow, said fuel flow path connectable at each end to fuel hoses; providing a rigid actuator pivotally attached to said pump body, said rigid actuator pressing on a spring-biased rigid piston and seal, said rigid piston and seal entering said pump body when said rigid actuator is depressed causing a precise amount of fuel contained in said pump body to flow into said fuel path and exiting said pump body allowing fuel to enter said pump body when released; providing a connection adapted to connect a first flexible hose connectable to a fuel supply attached to said first end of said fuel flow path; providing a connection adapted to connect a second flexible hose connectable to a marine engine attached to said second end of said fuel flow path, wherein said two-half rigid housing, said fuel flow path and wherein said rigid housing and said first and second flexible hoses are made from acetal material containing embedded particles having a hydrocarbon permeation of less then approximately 15.0 g/sq. meter/day.
