Fuel tank filler port cap with nozzle adapter

A fuel tank filler port cap with a nozzle adapter comprising:

• a cover base having an internal thread on a lower end to matingly attach to a threaded exterior of a fuel tank, an external thread on an upper end, and a central opening to access an interior of said fuel tank;
• an inner tubular sleeve slidably coupled within said cover base central opening having an outwardly protruding upper flange surface;
• a cover cap having an internal thread to matingly attach to said cover base external thread to cover said central opening;
• and,
• a twist and lift locking mechanism to move said inner tubular sleeve relative to said cover base, comprising:
• a plurality of curved receiving slots disposed at least partially through a bottom portion of an exterior side surface of said inner tubular sleeve;
• and,
• a plurality of pins protruding inwardly from an interior surface of said cover base superjacent to said internal thread;
• wherein an upper end of said inner sleeve is slidable between a lowered position generally flush with a top surface of said cover base and a raised position extending outwardly from said cover base top surface;
• wherein said twist and locking mechanism retains said inner tubular sleeve when in said raised position;
• wherein each of said pins insertably engages a respective slot and is slidable therewithin between said lowered position and said raised position;
• and,
• wherein each of said pins is stationarily supported within said respective slot when said inner tubular sleeve is in the raised position;
• and,
• wherein said inner tubular sleeve upper flange surface limits downward movement of said inner tubular sleeve relative to said cover base when in said lowered position.

A method of dispensing fuel into a fuel tank of a motorcycle, said method comprising the steps of:

• providing a motorcycle having a fuel tank;
• providing a fuel tank filler port cap with a nozzle adapter attachable to said motorcycle fuel tank, comprising a cover base having an internal thread on a lower end to matingly attach to a threaded exterior of a fuel tank, an external thread on an upper end, and a central opening to access an interior of said fuel tank;
• an inner tubular sleeve slidably coupled within said cover base central opening via a twist and lift locking mechanism comprising a plurality of curved receiving slots disposed at least partially through a bottom portion of an exterior side surface of said inner tubular sleeve, and a plurality of pins protruding inwardly from an interior surface of said cover base having an outwardly protruding upper flange surface;
• a cover cap having an internal thread to matingly attach to said cover base external thread to cover said central opening;
• and, a twist and lift locking mechanism to move said inner tubular sleeve relative to said cover base;
• providing a fuel pump assembly having a vapor recovery dispensing nozzle;
• threadably detaching said cover cap from said cover base;
• manually raising said inner tubular sleeve by simultaneously lifting upwardly and twisting said inner tubular sleeve relative to said cover base with said twist and lift locking mechanism;
• retaining said inner tubular sleeve in a raised position;
• inserting said vapor recovery dispensing nozzle within said inner tubular sleeve such that a lower fuel nozzle tip is within said fuel tank interior;
• filling said fuel tank interior with an amount of fuel;
• removing said vapor recovery dispensing nozzle from said inner tubular sleeve;
• manually lowering said inner tubular sleeve by simultaneously twisting and pushing downward said inner tubular sleeve relative to said cover base;
• and,
• threadably attaching said cover cap to said cover base.
