Several years ago I purchased a Benjamin Discovery when they first hit the market. It came with a hand pump which worked fine for a few years then quit pumping. I ordered a repair kit from Sum Optics and replaced the seals that fit (seemed like the kit had some extra parts in it) and the pump again worked fine for a couple years.
Now it has again quit working.
Can anyone recommend a source I can send the pump to and have it repaired properly?
BTW - the pump I have does not look like the pumps Benjamin is supplying today. The base looks different to me -

Sun did repair them, I have one myself that needs to be done that looks like yours

Here's a schematic for a Benjamin pump http://sunopticsusa.com/content/HP%20REPAIR%20INSTRUCTIONS.pdf (http://sunopticsusa.com/content/HP%20REPAIR%20INSTRUCTIONS.pdf)
If you think you can do it all yourself send me a PM and I can hook you up with all the appropriate sized orings for a complete rebuild minus the particle filter, orings only, for a few bucks.

Called Pyramid Air who gave me Sun Optics USA's phone number.
A call to Sun Optics and they will do a complete rebuild for $25.00.
It's on it's way to Sun Optics now!
