Great low pressure regulator
Purchased this several weeks ago and has made the best performance gains. Consistent even fuel pressure, gives great control. Only thing I would do is add a permanent fuel pressure gauge into the system to make adjustments easier. Trying to run the motor and make pressure changes with a general fuel pressure gauge is a little awkward but not terrible. I will look to holley in the future when I need fuel pressure control.

Excellent Addition
I have a 1963 beetle with dual crabs. It has to be set at 1.75 PSI to operate properly. I have tried all different kinds that VW people have recommended, but they all began leaking right away. I took a chance on this one and it works perfectly. Easy to install and even easier to adjust. Now I can actually enjoy this old beauty. Holley all the way and thanks to JEGS for carrying such quality items.

Problem solved.
The regulator solved the problem of flooded fuel bowels on my converted 4160 to 4150 390CFM 8007 Holley. On a well built 310 c.i. Ford in a 72 Bronco.

Great features easily installed
Product arrived on time. The product was easily installed. And was exactly four PSI as stated. But one of the greatest things is a rebuild kit is available through Jegs.

A good value
Does what it's supposed to for a low price. Don't forget that you'll need the brass fittings as well as they are not included. This is the second one I've purchased in the 1-4 PSI range as I am finding that my carburated vehicles are very sensitive to ethanol laced fuel.

Does Not work as it should
Output pressure goes up to input pressure. .my input pressure was 7 lbs ...Very disappointed in Holley..I thought I was getting quality, that is why I didn't buy an off brand product...
