Steve (or anyone else), I'm curious. Have you ever tried running a "fuel pump leaf" on a kart? The last time I bought kits from https://www.mfgsupply.com/ I bought one, but haven't tried it. The patent write-up refers to it as a "spring"... uh-huh, when was the last time you saw a spring made from aluminum? I'm guessing that it's just a blocker to limit the travel of the pump skin, but they couldn't get a patent for that! 
Nonetheless, maybe it does something useful?
Ditto for the 3 tiny springs on the pump check valves.
I'm including pics from the sled write-up, with props to the author, wankel303, whoever he may be!
