Hi guys. This is my first message and hope all u RCers can help me out.Anyway i made a third hole in the fuel tank for refuelling the tank because my plane(A CAP 232 by Kyosho) has a fixed cowl. Now i found another way of refuelling my plane by having two tubes outside the cowl( one from the tank and one to the carb) and want to seal of the 3rd hole which i made.I used epoxy but it looks like it is leaking. should i make the opening again and use a small tube with a screw or something to block the opening and prevent it from leaking?I have done this method without creating an opening in that hole which was sealed but the problem is that the fuel which leaks out has no other place to go from the tube and leaks out from that tube which was fitted with a screwinto the plane. I also have noticed that the epoxy placed at the 3rd hole is 'melting' and mixing with the fuel. will this damage the engine(having some epoxy in the fuel)? Please help!!

thank you.
