Adjustable FPR recommendation

What kind/brand of adjustable fuel pressure regulator is everyone using? not sure which one to chose. Keep hearing good and bad about every brand.

Holley 512-501 works fine and is easy to adjust.

Re: Adjustable FPR recommendation

My Holley was nice looking and was easy to install. Sadly it is now a paper weight. It lasted roughly 6 months before causing erratic pressure fluctuation.

Re: Adjustable FPR recommendation

I've had the Holley on for several years now with no issues. As stated, it is easy to adjust.
