Holley Performance Fuel Pressure Regulator; 1-4 psi; Standard; Chrome Finish; is rated 3.0 out of 5 by 1.
Rated 3 out of 5 by from Bought wrong part Did search on website for fuel pump, somehow ended up with a fuel pressure regulator. Not crazy about the way the website search feature works, but then again I should not take it for granted that it's correct and actually pay closer attention and read.
