Carburetor Fuel Regulators

A customer of mine is having issues with his Holley fuel regulator and his Sterling Nikki. He said he dialogged with another owner of a Sterling who experienced the same issue, but then another with a different carb set-up (I believe) who also had a problem with the Holley regulator.
I've been recommending the Holley 1-4 psi fuel regulator for years, and I had thought this to be the best. This seed was planted in my mind by Paul Yaws insistence upon his customers using that choice, as well.
I had also read many times that the popular alternative, Puralator, failed frequently due to a different diaphragm design.

Though I have cut into fuel pumps to see how they work, I have not dissected a fuel regulator, and do not fully know how they work. I'm assuming they work similarly to flammable gas (propane/acetylene) tank regulators, which I am a bit familiar with.

If anyone has any experience with regulators, please add yours here, and after some experience data is accumulated, I'll know better the parameters I need to set for a poll on this issue.
