I had a problem with the drain valve assembly being too long and contacting the top of my truck bed. Marty at ATC helped with shortening the original fitting so that the valve just cleared but that limited the swing of the valve lever so the valve would barely open. I found it very difficult to locally find threaded PVC fittings in 3/8" pipe thread. I found a 90 degree elbow and 2" long threaded nipple here: http://www.usplastic.com/catalog/item.aspx?itemid=22772&catid=726
This now clears my bed and the valve fully opens. Let's see how this works.
