No need to do the machining. Wick's has the items already made up. I used them for the quick drains and for my tank fuel pickup. One is sized to accept the strainer on the inside and the pickup hose on the outside. The aluminum stock to build them will equal their cost from Wick's. I also used the large fuel cap and ring but I didn't see it listed any more. http://www.wicksaircraft.com/catalog/product_cat.php/subid=977/index.html Bond them to the inside of the tank during construction. I used resin / flox to fare the edges and then probably two layers of glass to hold them. When installing the quick drains, sand down the foam to mount them in a small depression to insure they are the lowest part of the tank. For the pickup with the internal screen, mount the screen horizontal in the bottom of the tank. That allows maximum tank size for a given area while keeping all the fittings inside the wing plane. Again, I sanded out a small depression for the screen. It sets in a depressed area with approx 1/4" clearance from the bottom. That will insure the maximum useable fuel from the tank. When setting in a level attitude, my tanks will pump very near totally dry. Larry Flesner
