Hi Mike, Presuming you refer to the later Float and Dial wing tank gauge used in later Ercoupes, part. no. 48114 (no longer available), the 2" cork float was to be located 3/32" up from the bottom of the wire. It was secured in this position by two AN-960 CUI 3 washers soldered to the stainless steel float rod. You might want to put several coats of clear epoxy on your the new cork float (which may be coated with shellac) with before installation. I would solder it in position using washers. I'm not a big fan of cork gaskets for gasoline. Uninstalled stock shrinks as it dries out with age, so fit can be poor to start with. For gascolators, I like the neoprene ones, which give an immediate, leak-tight installation without goop. You are authorized to make certain parts for use on your own aircraft, and I would prefer a high quality automotive composition sheet material of appropriate thickness to cork. A high-quality gasket cement should be used sparingly on (only) one of the two gasket surfaces. Its purpose is NOT to seal (the gasket alone should do that), but to assure identical alignment after removal and replacement during maintenance. Mark parts like valve covers before removal so they get reinstalled in the same place in the same orientation for maximum gasket life. Gauge gaskets are easy to make. Insert a 1/4" handle X-acto knife in a cheap compass designed to hold a wood pencil. First, individually cut as many 2-1/2" circles from your sheet material as you want. Then, using the same point hole (maybe with a wood backer as "accuracy insurance", cut the 1-1/2" inside holes. Stack the gasket "blanks" with your metal ring on top on a piece of wood you can secure in a vise. Drive a small nail thru two opposing holes (to keep all the gaskets aligned on the wood), leaving sufficient nail projecting for later removal. Drill all the open holes. Place a fine wood screw through two opposing drilled holes to keep the gaskets aligned. Remove the two nails, drill the holes where they were to size, and you're done. Regards, William R.
