The holes are very small about half inch in dia while the metalic tank is inside the walls of the wings. The sealant has blocked the holes inside the wings. water o high pressure air is not working in it. There is no access as its a blind tank from all sides, except the available ports of fuel...
i am facing a problem where the sealant has blocked some of the internal vent holes inside a blind metallic fuel tank. The tank has only inlet and outlet connections available for access. Can anyone suggest some solution how to get rid of sealant from this area.
thanks
