I take apart the trunk and there is a 50010 on the outside of the fuelpump cover but also there is a ND which I assumed was Nippendenso. I call Lexus and they say 50010 is Asian...but I explain the emblem engraved into the metal and then they say it sounds like a Nippendenso?? They are confused as well!

Hello fellow genmayer

Aisan is another supplier to Toyota. They specialize in fuel/emission parts. They supply OEM to Toyota throttle position sensors, throttle bodies and throttle dashpot closers.

Denso parts will say ND DENSO, NIPPONDENSO or just DENSO. Aisan is in script, here's their site: http://www.aisan-ind.co.jp/english.htm
