storm pneumatic designs Leak

I bought a storm with a group of other markers. I've searched for diagrams and manuals everywhere to no avail. So I'm asking the experts. The marker is leaking down the tube near the hammer. Both the hammer and bolt have orings. But thats it for the internals. Other than the spring and striker spring guide, none of no other internals come out. i'm thinking its a cup seal, but I got no idea where to find a new one at or what it looks like. Help please.

The valve has a stubby power tube, a la nelson. That can bend and crack easily. The cup seal mounts the same way.

The valve body orings also start leaking with age.

To get to the valve at all is a trick. It's really hard to remove the volumizer because of the inevitably swollen oring on in. And the valve takes a special tool that came with the gun's original packaging.

Good luck!
