primer pump leak
I'm replacing the primer pump. When I installed the new one there is a slow dripping leak where the pump is screwed in. I've tried several different primer pumps (I have 3 on hand). I've tried with one copper washer and two copper washers. I have tightened them fully. Every time I try, I get a drip from where the primer pump screws into the holder on the engine. What could the problem be?

I only get so far with the magic eight ball.
