I’m hesitant to write this review because of what I’ve read about this part failing after a short amount of time/milage. I’m probably about 500 miles into this new pressure regulator and it still seems to be working just fine. I have much better throttle response time as opposed to my original busted one. My truck cranks right up without any issues. Installation took less than 10 minutes. It would have been quicker if I didn’t need to fish out the old o-ring from the bad regulator. Just make sure to depressurize your fuel system before trying to replace it. I thought I had done a good job at it but it still spit a little gas at me. Other than that, this part works like a dream. I’m glad I purchased it. I haven’t had any of the noise that some reviewers state but maybe that’s because I don’t have active fuel management like some newer vehicles? I don’t know. But mine works great. I recommend it.
