those style cup seals can be found here. Kingman Hammer Pump Synthetic Cup Seal (5 pack) - I&I Sports
put pretty sure any spyder cup seal would work ??
on a side note has anybody else stripped out their feed neck on the direct feed ? I have on two bodies in the last year. I guess my stick feed fits too tight inside the feed neck. Maybe my next one will go on the outside, fit loosely and maybe use a set screw. Just ordered a new body from ii for $9 on ebay.
