Ok so I received my qev and my shock pump. I was very excited to build my air rifle so I went out and bought all the parts, Pink teflon tape(stronger than the white) and taped up the threads, screwed it all together and I went to go pump it up and... It leaks! Not the gun the shock pump!!! Its brand new I have been trying to fix the leak for a week! it looks like this
http://www.google.com/imgres?um=1&hl=en ... 2,s:0,i:88

It leaks out of where the hose connects to the pump. I tried screwing it on tighter and that didn't work. I tried putting Teflon tape on the thread and that didn't work I was messing around with it for over an hour and it wont stop leaking anyone got some tips???

Is it possible that there is a bleed valve, like on high pressure pumps?

it leaks out of there. Either the hose it self or where the brass piece screws on.

Check it with soapy water while pumping. That will tell you where the leak is from.
