Great part
Works as it should. Reads my e85 perfectly.

Authentic
No complaints with the quality. Appears to be authentic. Fits as expected and is still working in my high horsepower car. It's been installed for at least 5 months now and is still accurate. No leaks and is easy to install.

Solid sensor
Almost got the more expensive one with the mounting bracket but decided to roll the dice after reading some peeps haveing issues out the box, luckily worked for me. Added sensor to a 08 non flex Silverado once hooked up was reading 10 ish % on pump gas, first fill up on E and percentage started climbing leaving the station. Side note I had to change injectors as well to run e, I went with 50lb. I’ll be changing fuel pump down the line.

Description of the product could use some refining. But this is an AC Delco (Continental) OEM GM flex fuel sensor.

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.

Sensor I recieved is not an OE gm sensor and failed immediately on install. When compared to a true oe sensor the visual differences in the part numbering and logo is apparent. Also the coloring of the plastic is not true to a gm part.
