I have put a small yard ball (childs, 1.50 at the toy counter) with the standard ball pump spike modified with extra hose into the tank through the sender hole, blow it up, pat the tank at the creases with a slapper, let out the air and VERY carefully pull it back out. I use welding rod to push it into position. If the fill spike comes out with the ball in the tank just poke a hole in it and pull out with a hook.
