Hi, need some help from you guys.

My power tube cracked, so the owner of the store recomended a JSC power tube- I got it real cheap, 30 % off. So what the hell, I bought it in good faith.

But the valve didn't go all the way in, but after some minor adjusting and some work with the sand paper it fitted just perfect.. But then, when I screw'd on the HPA tank I can hear the power tube leaking. The leaking sound is coming from the front (where the barrel goes) of the gun.

got any ideas what I could do to fix the problem?

Thanks.

Check to make sure you didn't get any debris in the valve from the sanding. Also, did you tape up the threads on the hoses before you screwed them back in? If not then that may be your answer.

Your valve is most likely leaking. If you screw in the two screws that hold the power tube in place too far you can squish your valve wall. It can then become disfigured and air and leak through it. Take your valve apart and check over really good.
