Mine just arrived
I was looking them over and noticed the entry and exit have a bit of a lip from the inner tubing. Yours look the same in your photo, spearfish. Think it's worth grinding it down a bit to make it a smooth entry and exit? Also the flanges on the entry have a little curve to them but I think they'll be fine once tightened down along with the gaskets. I'll post up some pics in a bit.
P.S. Not trying to take over your thread, spearfish. ERZ said they wanted to try and keep all the info in as few threads as possible
