Abstract
A fast fill system is provided. The fast fill system includes first and second high flow roll-over valves, each coupled to flexible tubes. The system includes a replacement fuel tank with first and second inserts on top. The high flow roll-over valves couple to the replacement fuel tank through the respective inserts. The valves with flexible tubes allow the replacement fuel tank to expel up to 400% more air when refueling than without them. This enables filling by high-flow truck stop pumps at rates of 25+ gallons per minute without pressure buildup or spillage.
Claims20
A fast fill system comprising:
- a first high flow roll-over valve;
- a first flexible tube coupled to the first high flow roll-over valve;
- a second high flow roll-over valve;
- a second flexible tube coupled to the second high flow roll-over valve;
- a replacement fuel tank comprising a first insert and a second insert on a top of the replacement fuel tank, wherein:
- the first high flow roll-over valve is coupled to the replacement fuel tank through the first insert;
- the second high flow roll-over valve is coupled to the replacement fuel tank through the second insert;
- and
- the first and second high flow roll-over valves with the first and second flexible tubes are configured to allow the replacement fuel tank to expel up to 400% more air when refueling than without the first and second high flow roll-over valves.
A replacement fuel tank comprising:
- a tank body formed of high-density cross-linked polyethylene;
- a first insert and a second insert positioned on a top surface of the tank body;
- a first high flow roll-over valve coupled to the tank body through the first insert;
- a second high flow roll-over valve coupled to the tank body through the second insert;
- a first flexible tube coupled to the first high flow roll-over valve;
- and
- a second flexible tube coupled to the second high flow roll-over valve, wherein the first and second high flow roll-over valves with the first and second flexible tubes enable the replacement fuel tank to be filled by high-flow truck stop pumps at rates of 25+ gallons per minute.
A method of installing a fast fill system on a replacement fuel tank, comprising the steps of:
- removing a plug from a first insert on a top of the replacement fuel tank;
- removing a plug from a second insert on the top of the replacement fuel tank;
- setting up a system to catch plastic shavings;
- drilling a first hole in the first insert;
- drilling a second hole in the second insert;
- trimming inside edges of the first and second holes;
- cleaning the replacement fuel tank of debris;
- threading a first high flow roll-over valve into the first hole;
- threading a second high flow roll-over valve into the second hole;
- coupling a first flexible tube to the first high flow roll-over valve;
- and
- coupling a second flexible tube to the second high flow roll-over valve.
