Abstract
A fuel surge arrestor can include a funnel shaped to fit within a fuel fill receptacle of a craft. The funnel can have a nozzle opening for accepting a fuel fill nozzle. A vent can be located at a top opening of the funnel. The vent can include a plurality of baffles that enable airflow within the vent while deterring heavy vapors and liquids from exiting the vent during a fuel surge. Various stems having different outer diameters designed to fit within various-sized fuel fill receptacles can be removably coupled to the funnel.
Claims12
A fuel surge arrestor for use on marine fuel-powered crafts, comprising:
- a funnel having a nozzle opening, the funnel fluidly connecting a removable vent and a stem to create a fluid pathway, the removable stem insertable within a fuel fill pipe and including at least one ribbing element for establishing a seal with the fuel fill pipe, wherein the vent comprises a plurality of offset overlapping baffles positioned within the vent and extending from a wall of the vent to partially occlude the fluid pathway;
- and an additional stem removably couplable to the funnel for replacing the removable stem on the funnel, wherein insertable portions of the removable stem and the additional stem have different diameters.
A method of refueling a marine fuel-powered craft, comprising coupling a stem to a funnel of a fuel surge arrestor, wherein coupling the stem includes selecting the stem from a group of stems having insertable portions with different diameters;
- inserting the stem of the fuel surge arrestor in a fuel fill receptacle of the marine fuel-powered craft, the funnel of the fuel surge arrestor having a nozzle opening, the funnel fluidly connecting a vent and the stem to create a fluid pathway, the stem including at least one ribbing element for establishing a seal with the fuel fill receptacle, wherein the vent comprises a plurality of offset overlapping baffles positioned within the vent and extending from a wall of the vent to partially occlude the fluid pathway;
- inserting a fuel fill nozzle in the nozzle opening;
- and
- fueling the vehicle using the fuel fill nozzle.
A fuel surge arresting system for use in a marine environment, the fuel surge arresting system comprising:
- a fuel surge arrestor comprising a funnel having a nozzle opening and a stem receptacle, the funnel fluidly connecting a vent and the stem receptacle to create a fluid pathway, wherein the vent comprises a plurality of offset overlapping baffles positioned within the vent and extending from a wall of the vent to partially occlude the fluid pathway;
- a stem removably couplable to the stem receptacle, the stem insertable within a fuel fill pipe and including at least one ribbing element for establishing a seal with the fuel fill pipe;
- and an additional stem removably couplable to the stem receptacle, wherein insertable portions of the stem and the additional stem have different diameters.
