Mounting a 11 gal spun aluminum fuel tank in the bed of my Study and am looking for a sending unit and probably a mounting "bung" for it as well.
Any suggestions?

Aircraft guys have weldable pieces available. Check out Wicks Aircraft and/or WagAero. Sniper
For under $30 JC Whitney has an adjustable sending unit and matching gauge. As for a mounting bung, the easiest way is to weld an aluminum plate to the tank for a bung. If you don't have a tig, then here is a "poorboy method".
Drill the hole for your sender unit to go though in the tank. Easiest way to size this is to use the inside circle on your gasket for the sender. Now, take a hole saw that is just bigger than the outside diameter of your sender gasket and cut yourself a circle in 3/8" or 1/2" aluminum plate. Then take the hole saw you drilled your tank hole with and cut out the inside circle on that aluminum plate. Now, take your sender unit, and making sure your float wont hit anything when mounted, mark out the mounting holes on your aluminum plate (usually 5 of them). Find 5 "self tapping" screws that will go through the sender and plate and deep enough into the tank so there are threads grabbing.
Next, drill out the 5 holes you marked in the plate so that the self tapping screws will go through cleanly withough the threads trying to thread into the plate. After you drilled those holes in your plate, take a grinder and (take your time) grind out the bottom of the aluminum plate so it matched the radius of the tank. Cut out a nice thick cork gasket to go between the tank and the plate. Adjust your sender height. Then put the cork on the tank, the plate on the cork, the gasket on the plate, the sender on the gasket and screw it down. [cl
