Benjamin wildfire air leaking out the barrel

I second mscottleeman. My old career used to do that. Try cocking the gun slowly while filling the gun with air. You may have to dry fire a few times while doing this. Try it and pm me if it doesnt work. Oh are you using a hand pump or a tank? If your using a hand pump it will be more difficult. If using a hand pump try dry firing and if it still wont fill cock the bolt open and pump a bit to loosen the debris. 
 
So question again. I finally have time to work on the wildfire and the air tube does not hold air. It just leaks out. So the question is does this tube have 2000psi to it at all times?
