I've made use of a marine outboard motor fuel tank, OMC fittings, hose with bulb and modified the gas cap on my Honda eu2000i to accept one of the OMC fittings. Hooked it all up, squeezed the bulb a couple of times, generator started, ran for a couple of minutes and stopped. Pumped the hose bulb a few more times, generator ran a bit longer and stopped. It seams that the generator isn't drawing fuel from the tank. This Honda model has a fuel pump so it should work. I didn't have the tank vent closed. Could this be the problem? No other indicator lights came on like low oil or overload.
