I used a 15" piece of 7/8" .065 cromoly tubing to bulk my 2240. I pressurized it to test for leaks and it seems to be leaking by the new Max flow valve face. If it were the valve seat, the leak would be coming out the barrel right? The leak is coming from the body. I polished the inside of the tube with fine steel wool on a stick in a drill. Came out very shiny. I also put some oil on all the O rings. Do I need to get a larger O ring?
