I put a valve on the end of a bulb-type gasline from a 2-1/2 gallon outboard tank and used it to pump
fuel into the little tank on the Honda when empty or nearly empty. I think it took about 10 squeezes. Not as easy as having a big tank feeding the engine
, but a lot easier and safer than filling the little tank with a jug. The valve just keeps the line from leaking fuel when not actually in use.
