4*60 ARF fuel tank?
You should have no problems installing the tank as per the instructions. This is a fabulous plane and it flies like it's on rails! I have about 40 flights on mine now and have had no problems with the tank. Make sure that after about 5-6 flights you tighten the stopper. I have found that they tend to come loose from the fuel and pressure.
