If you notice line coming out of the bottom of the Retriever in front of the bottle, your stripper needs adjustment not replacement. To adjust your stripper, loosen the screw above it and below it. Push the Stripper downward toward the bottom of the Retriever body until the handle won't turn. Then push the Stripper up just enough so the handle turns freely and hold it in place. Tighten the lower screw first, then the Trigger screw. Do not over-tighten.
