Honda EU1000i Extended run time gas cap

thingiverse

Experimental users, be warned: this design is untested and prone to extended runtime issues. You're on your own for safety, insurance, and regulatory compliance. The Honda EU1000i generator operates for 3 to 7 hours on its internal 2-liter fuel tank. During an extended power outage, you'll need frequent refueling, a tedious process that quickly becomes old hat. This design takes advantage of the generator's built-in fuel pump to draw gas from a larger portable 5-gallon gas can. The hose barb is designed for use with a 5mm ID silicone rubber hose. To create an air-tight seal between the generator's gas tank threads and the printed gas cap, you'll need to install an O-ring. The print must also be non-porous and compatible with contact from petroleum-based gases. If issues arise, consider drilling out the hose barb and replacing it with a simple metal tube using epoxy. You might also add an aluminum foil liner to prevent gas from coming into contact with the print's surface or any potential seams. To assemble the design, flip the nut over and print it. My testing will have to wait until the next big storm rolls in and power outages become a reality. This design was created using Fusion 360 and printed on a Cetus mk2 extended. The results were inconsistent due to a faulty spool of Hobby King filament - a valuable lesson learned.
