Yeah, if the float valve sticks open fuel overflows out that hole and can 
splash on something hot.  On MGAs these vents are metal tubes that 
redirect overflow to the ground.  If I were you I'd leave it like it's 
supposed to be.  If you can't live with this do the MGA type thing to 
prevent danger of fire.
