Leaking air somewhere. Changed valve and it will not hold air. Did get some leaking through barrel but also around fill port. Need help. Thanks

Leaking out barrel muzzle 
and breech (when side-lever open) means broken valve core (picture.) If you've replaced valve, did you burnish new valve to valve seat? Best illustration of burnishing is Hajimoto's YouTube on installing performance kit in Umarex Gauntlet.

Did you cock the gun when you filled it? Try cocking and firing a few times then cock gun and see if it will fill. You can spin the poppet on the seat or whack it lightly with a dowl rod to try to seat the valve. Just a speck of dirt can cause it to leak so you may have to pull poppet and clean it.

Ok broke the gun down more looks like there a piece of metal bent up or something where the valve seats. Looking at valve looks look it made an indentation on it. Can this be filed down. Maybe when valve broke it hit that area and deformed it some. Gun never leaked before I changed valve stem

So found a dremel polishing tip that fit perfect but only had polishing compound was able to get some of the imperfections out and had an oring to fit bottle adapter. Was able to fill. I'll see if it holds air tonight. If not ill get lapping compound and try again.

So did that fix it? I had one that leaked like that and it took forever to get it to seat, I ground a round stone to 45 degrees and honed it with a drill and finally got it to seat to a valve. What did you do?
