    12-807 is rated 4.8 out of 5 by 4.
    Rated 5 out of 5 by from Great improvement My fuel pressure regulator was very old and required the adjusting screw to be nearly all the way out. I got this kit to refresh it and now the adjusting screw is back to a more normal spot to maintain the 5-1/2# to 6# fuel pressure. Great refresh instead of buying a new regulator!! We'll have to see how long it lasts.

    Rated 5 out of 5 by from Great Money-Saver Why purchase an entire replacement regulator when you can easily rebuild your old one? Mine's over 25 years-old, and is still in use!

    Rated 5 out of 5 by from Great product The Holley regulator kit allows their regulator to be refurbished to new condition which is the way parts should be designed rather than being throw away parts. The kit also enables the regulator to be changed for various pressure ratings
