Abstract:
1. A primer pump for use on a fuel line for a marine engine comprising: a rigid housing containing a pump body, a 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 fuel flow path connectable at each end to fuel hoses; a rigid actuator pivotally attached to said housing, said 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 fuel contained in said pump body to flow into said fuel path; and wherein said rigid actuator is mounted directly on top of a cup-shaped piston guide, which fits onto an outside surface of a generally cylindrical piston housing with a protruding extremity at an upper end of the pump body; a first flexible hose connectable to a fuel supply attached to said first end of said fuel flow path; a second flexible hose connectable to a marine engine attached to said second end of said fuel flow path; a slot and tab mechanism between said piston guide and said pump body that prevents said piston guide from separating from said pump body.
