This is from the Milodon instructions:

Pickup Assembly – The pickup whether swivel or static will attach the fittings in the same
way. The fitting is a “bulkhead” style that has a groove cut into the long thread section that
the O-ring will sit in. Use a little oil on the fitting threads so avoid galling. With the jam nut
and the washer threaded onto the fitting, slide the fitting through the holes in the pan. The Oring
will then be installed on the fitting inside the oil pan. Align the O-ring on the unthreaded
groove. Use the jam nut to adjust the fitting position in or out to correctly align the O-ring in
its groove. Slide the pickup up to the fitting and screw the fitting into the pickup. The final
tightening will be by the jam nut once the desired fitting angle has been determined.
When using the swivel pickup, make sure that throughout the pickup’s sweep forward and
rearward is kept at an even ¼” to 3/8” all the way through. That is not ½ at one end and 1/8”
at the other.
