Heres what I was looking at. Its the annular fogger. It doesn't fit into the runner very far and depending on your runner configuration, it can be installed at a lower 30 degree angle vs the usual 90 degree. You can't see it in the picture, but the end has a square notch.
Now the plan is to drill out steel rod to 0.242" and then use a 1/16-27 NPT tap to make the bungs. Then weld them in at 30 degree angle. Pics to follow.
Sorry about the red X's above. I moved some pics around on my site.
