Just a lil' fore-warning: (I've learned this the hard way) J.B. Weld and Aluminum expand at different rates when heated... this causes the bond to break, and an air leak to develop.

If the J.B. is accessible, I would put a layer Permatex Motoseal over it to be safe. Fuel resistant, high temp. and flexible....
