Steve, was that the allen plug in the upper left side of the case that you used? Did you bore i ou to a larger size to get AN fitting on i?
Yes, I just removed the threaded allen plug and moved it to the lower location. Both are 1/8" NPT thread, no need to increase the size of the hole. I then used an 1/8"NPT to AN6 fitting with an AN6 90 to the hose. And of course the hose needs shortening to allow for a constant 'up' elevation change to the tank.
