RagingBull leaking gas
 

My raging bull is leaking gas from some where near the hammer when it is filled. When i try to fill it i can hear it comeing out from around the hammer and it wont hold any gas. has anyone ever experinced this problem or know how to fix it? does anyone know where i could find a break down picture of all the parts?

i have and unfortunatly the tube has most likely popped loose
