    I'm thinking an aquarium air pump would do the trick. (going to find one that runs on 12 volts)

    Ordered: https://www.ebay.com/itm/12V-DC-R38...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

    Now, to design and 3d print a chamber that the O2 sensor screws into and has an inlet for the sampling hose and output to the air pump to draw gasses over the sensor. Heat from the sensor is my biggest concern. Maybe plastic will be the prototype of something that can be machined.

    this is all dependent on a 6mm stud(5mm minor diameter) with a 4mm hole through it. so now the stud has a .5mm wall, it's not very strong.
    how much exhaust is going to go through a 4mm hole? enough i hope
