AC Delco GM OEM Part
Description of the product could use some refining. But this is an AC Delco (Continental) OEM GM flex fuel sensor.
User
Lacking precision
Tried to make it work properly over several days, kept switching between 2 and 10 % alcohol content, finally switched for a bigger Continental model, and this one worked properly. I don't know if it was a bad unit, or if it's just cheap and imprecise.
