Is there any particular reason why you decided to remove the stock trigger valve? Ball valves are very slow to open.
On another note, hot glue should never be used under pressure. It will tear itself apart, and probably take something with it. At the very least, I suggest that you use epoxy.
Also, could you provide some more information on the blaster itself? It appears to be a water gun of some sort, which would explain the large tank, small pump, cap, and the large number of pumps required to build pressure in the tank.
I owned one of these, recently threw it out. It was part of a set that had a water blaster and a glove+handle. The water tank came out, and was replaced by a bottle of silly string that looked like web. It strapped onto your arm, and you pulled the stock trigger down with a spiderman like grip. Was awsome to run around and shoot web like a hero.
The straps it comes with stopped fitting around my arm when I was 6.

WTF, are you in Tony Stark's basement!?'
