This was used to repair a Porter Cable FN250A that I had purchased. After some internet research, I discovered that my nailer was firing blanks, so I disassembled it and discovered that the older bumper had disintegrated. It appears to be working much better now that this part has been replaced. It’s still misfiring, but I don’t believe it’s because of this part. It’s possible that I still have an air leak somewhere.
