Filling this tank got real old. REAL QUICK. I ordered a good quality fuel grade rubber syphon hose/ hand pump/ with hose clip included, from AMAZON. ( There many to chose from. Choose carefully. Most are cheap crap. I keep several filled five gallon fuel containers in my garage. I fuel my bike up at home by placing the fuel container above the level of the bike, running the hose from the container down around the mirror, and throttle grip, into the bike tank so it can’t slip out. Test that it’s secure before pumping the siphon ball. I put on surgical gloves to avoid hand contamination. And roll up the drained syphon, storing it in a large ZipLock bag. Do it correctly and you’ll never spill another drop.
