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.
