A fuel filler module fits in the filler pipe of an automotive fuel tank and includes a spring biased trap door that cooperates with a fuel nozzle restrictor to seal an open end of the filler pipe automatically when a fuel nozzle is withdrawn. The fuel filler module also includes a fuel nozzle guide that is part of a vent system for venting the fuel tank during the refuelling process and a splash guard feature that prevents splash back at the end of the refuelling process. The fuel filler module comprises four-snap together components that are largely plastic parts or assemblies of plastic parts that are designed for easy molding to facilitate economical manufacture.

Why it's free to use
- Filed November 26, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 26, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 26, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
