I hope I dont run into that. I have a YS .63 that has 5 tanks run through it. Are you going with a stock one again??

I screwed the nuts on as far as they could go, then screwd the 90 degree elbow in as far as it would go, then unscrewd the 90 as it screwed into the muffler piece. That is the only way I could get more then a few threads holding anything together.
