ABSTRACT:
A hand operated primer pump for small marine or other engines generally spark ignition engines used on stern drive boats that prevents transfer of hydrocarbons into the atmosphere. The primer generally mimics and replaces prior art rubber primer bulbs in general shape and possibly color, although it can be made in any shape or color. It generally contains a pump that delivers a precise measured amount of fuel with each stroke of the actuator. The primer can have an ergonomically designed actuator that creates the farthest distance from a fulcrum point for maximum leverage and hence, maximum ease of use. The primer is generally designed with a continuous molded fuel path to seal any source of hydrocarbon leakage as well as being made from materials that prevent transfer of hydrocarbons to the atmosphere.
