    Rated 5 out of 5 by from 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.

    Rated 5 out of 5 by from 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.

    Rated 5 out of 5 by from 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.

    Rated 5 out of 5 by from 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.
