sometimes between the pump and the line, there is lots of fuel in there, if it really bothers you, pull the rubber supply line off the pump, and stick a 3/8 bolt in it. that's what i always do. dont' be too scared, although i'm sure safety nuts will jump all over me, it's highly unlikely that the fuel will catch fire, even if it hits very hot parts of the engine. a few weeks ago, i was taking my 1981 harley shovelhead chopper out for it's maiden voyage after i chopped it. during the process i installed a different tank, and made mounts for it. the weld on the mount caused a tear in the thin sheet metal of the tank. I rode for 30 miles with gas PUKING all over the engine without knowing it. then i pulled over to meet some friends, and they pointed it out to me. I freaked out, and thought it would catch fire. the gas was sizzling as it landed on the head. it had a very nice stream of fuel dumping right on to the hot engine. well, for about 15 minutes, i tried to keep it off the motor using my shirt, socks, etc. after that, i literally gave up. it's insured, let it burn, and walked away and waited for the tow truck. 4 gallons of fuel dumped on the hot motor for a hour before it was finally empty. and when it was empty, i touched the motor, and it was still way hot! no fire, got luck (or unlucky, insurance $$$ would have been cool!)
