A ullage system for a marine fuel tank that maintains an exact ullage space in all marine refueling situations including refueling in moving or pitching and rolling situations. The invention includes two ball valve assemblies that are inserted into a fuel tank at approximately the same level. The two assemblies typically are at opposite ends of the tank. One of the ball valves is smaller than the other in diameter. The smaller valve is coupled to an air vent; the larger valve is coupled to the filler tube. An important feature of the present invention is that it can typically be made to fit any marine fuel tank simply by changing the length of a vent tube to reach the correct ullage level for the tank at hand. The components of the present invention can be made from standard fuel valve materials.

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.

Abrégé

A primer pump is provided for use on a fuel line for a marine engine. The primer pump includes a rigid housing containing a pump body. A fuel flow path extends through the primer pump between an entrance check plunger and an exit check plunger, and the fuel flow path is connectable at each end to fuel hoses. The rigid housing includes a right half shell and a left half shell, which close around the pump body and check plungers. In use, a first flexible hose connectable to a fuel supply is attached to the first end of the fuel flow path and a second flexible hose connectable to a marine engine is attached to the second end of the fuel flow path. A rigid actuator is pivotly attached to the pump body for selectably causing fuel contained in the pump body to flow into the fuel path.
