You know the cap has two positions right !? The cutouts dictate where the cap can be applied, then turn clockwise (righty tightly) the first step is like 1/8 of a turn, light pressure. The second step is another 1/8 (for a 1/4 turn in total) this second step has more resistance & sets the spring pressure on the pressure seat seal. I suspect you are only at step one !
