I got my old leaky sm3k about a week ago. I modded it with nested petg barrels, externalized the pump (rotation mech was broken anyway missing pieces) I put a piece of PVC for the trigger to slide on.
Now, when I pump it 5 times, it shoots 5 feet. I think its an issue with the pump handle, as when I pump it, it makes a hissing noise. Ive triple checked all the connectors to the pump and the tank, there are no leaks.
Any suggestions? ive plugged the pump in all ways possible, short of emptying a tube of goop down the back of it.
Thanks

If you put the gun back together incorrectly, you may have a hard timing pulling back the trigger resulting in a slower pull. Internal pics would help.

Ok will post some.
Here is the pump
Here is the trigger mech
Here is the turret.
Here is the sealed airtank.
Sorry for the bad pics, I have like a 4 megapixel camera.

It's just screaming to be rearloading...
I seen a movie about that once.

It seems to be a problem with the air tank, what this is however, I do not know.

I figured out that without the auto rotation system, the turret isn't snug against the tank. So in other word, I decided to single it.
Just waiting for the epoxy to dry.
