Hello everyone. I was just wondering if anyone has developed an aftermarket solution for the silver box that runs inline with the fuel sending unit and the digital gauges. From my understanding the sending unit for the digital dash is discontinued from Nissan because the stock on those silver boxes dried up.

I have heard that a user from another z31 forum was working on an Arduino solution, but I am unable to log in to that forum for some reason to inquire about the status of the project.

Does anyone here know about this or any other similar problem? I would totally jump on this, but I have zero experience with Arduino nor am I confident in my multi meter.

Mine went out, not sure if you ever got this fixed or not but z321partsforyou.com has this part and they assure you that it is working order. pretty cheap and easy swap
