I have some if you need them. Already preorganized per the breakdown in the support equipment gate. If you are still looking for some let me know and we can work something out.

I got a kit from Sun Optics the official repair facility for the Benjamin pump. If I remember it was only about $10 and came with instructions. The only o-ring that needed replacing on mine was for the final stage I think. All the black goo that covers your pump stages is the o-rings disintegrating is due to the heat and friction although it looks like its dirty. I cleaned mine up and polished the rods with Mothers Metal Polish to try and offer less friction. I got the kit from Sun Optics but only needed the one o-ring. The one Sun provided was white and supposed to be the new and improved one and it has not failed yet for a couple of months and i use mine to 3000 psi regularly. I don't recall the part number but it is the one that fails most often from reading some of the other posts on the subject. The folks at Sun are top knotch and very friendly.

You can get the kit from sun optics but I would look into figuring out their sizes and ordering orings ment for heat and pressure

Thanks to this thread, I contacted sun optics, and they sent me a rebuild kit plus the spring for free! I simply asked how much it would cost and the customer service person told me they would send it out free of charge. I hope I don't have to use it any time soon, but if I do, it will be on hand, and I won't have to wait!
