I had this pointed spear sticking out the side of the fuse. The blood made more of a mess than the fuel did...........
Sorry to hear that. I go over mine with fine sandpaper to round off the end and eliminate any sharp edges. Also I keep a red plastic cover on them when not flying; not so much for protection but to keep any fuel from dribbling out when loading/unloading or carrying the plane up the from the basement.
