Kirn Kraft Products- Whats that thing??

Hey! Does anyone know if Kirn-Kraft ever published a catalog or pictures  of his products or anything to Identify what an item might be?
 In my last batch of engines/parts purchased there are a couple of plastic bags with hand typed labels like:  KK-04   20.00  and  KK-72  .25   also includes in unmarked bags 3 different types of Needle Valves,  OEM, Texas Timers style  and blue plastic one.. Any Idea on what one  that might be?  
The Lapping tool by Kustom Kraftsmanship looked like a good idea, but the con rod still spins as you tighten the nut, so the piston won't spin as you lap the cylinder...masking tape on the end of the tube still works though.  
The last picture is of what I guess to be springs for the ID of the fuel pick-up in a tank? but I'm not sure what the thin u shaped wires are for. you have any guesses what they might be?
