Something wrong with my 2009 Spyder Electra paintball marker?

Ok, I have a high pressure Pure Energy 48Ci 3000Psi tank and a 2009 brand new Spyder Electra. I fill up my tank and put it on my marker which is a on/off asa. Whenever I turn it on the air goes through as normal but it leaks through a hole on the foregrip. Their is a little hole on the handle which is supposed to be their. I opened up the grip and replaced all the O-rings yet it still happens. What can I do to fix it?
