I was filling up yesterday and a hornet landed in the hollow space around the fuel spout. I figured he would fly away or I would flick him away after fueling. Well, I couldn't find the bugger. I looked under the rim. Nothing. Just when I thought he must have flown away, I see his butt sticking out of the little overfilled drain hole. He was already in deep and was pulling himself in further! By the time I got a pin to shish kabob him, he was in all the way. Darn Hornets.
I think the compressed air idear should work, but if you don't have a compressor handy you could try a blast of WD40...the little red straw will direct the stream in the right direction...and hopefully blast El No Me Gusta Hornet right out the bottom of the drain tube!
Or, dont worry about it...he was probably overcome by fumes and has since expired in there. he will dessicate and then disintegrate as insects will, and eventually the pieces of his dried-out exoskeleton will work their own way out.
At least the damn things didnt try to build a nest in your bike!
Well, fire the engines! Spur this iron space-pony on!
