Works great
It was a perfect fit for my 2017 Chevy Cruze. Just like factory. It was a GM product

Best price, fastest shipping and good quality parts
I bought four and replacement them with the fuel rail. My 2017 chevy malibu is running great again no leaks. Amazon was able to sell them cheaper and ship them faster than. Auto zone, O'Reilly's, Napa and even rock auto! $80 each is what I paid for them in Feb of 2025. I will post an update for this review if I have any issues within the next year

Horrible
Not happy at all with this purchase. Item was used. Part number on box did not match part inside box. It was an important part I needed to fix my truck. Had to buy another one elsewhere.

It worked.
Came in a genuine gm parts box. Looked exactly like the one I pulled from the car. Plugged it in and charged the fuel system. Fired first try. Best price around as well.
