r.a said:Here's the inside of my pump with the peg (top photo below). Compared to the photo provided by GuidoK is seems mine is missing a part (the metal tube/sleeve that surrounds the peg). I think I may have lost this part as there is a lot of play when the peg sits in the hole in the white plastic. Please can someone confirm?

To me the inner seal looks damaged especially just below the fig.4 Perhaps this is how air is able to enter.
