I've used Aeromotive regulators on both boost regulated for a supercharger application, and for Throttle body fuel injection. Just had to change the spring to go to the 40lb level. Very reliable, and accurate. Both dead ended and return line types. Be sitting down when you check the price, but they work.

I have a 3x2 set on the 312 Tbird using Holley (Ford) 2110 94 carbs. Stock fuel pump and no pressure regulator. Tends to boil the fuel bowl on hot soak or leaks down after a sitting for a couple weeks. Hood clearance won't allow for phenolic spacers so I just deal with it. In the beginning I tried a couple different regulators. Both were crap and wouldn't hold a steady pressure. Threw them in the trash.

I am running an Holley FE fuel pump and a 3x2 set up. The Holley 94s hate anything beyond 3 PSI of fuel pressure. I am using an in line regulator to dial it back, it is a little cheap dial one that has been working great. I do have a dial gauge tapped into one of the banjo fittings that is pretty close, for detailed checking I have a T fitting in the line that I can hook a regular pressure gauge to check/adjust.

Ted & Charlie  thanks for the replies. I did some other research online and was advised to not use a liquid filled gauge because they will change readings with temperature change under the hood. This am I started over with trying to adjust the regulator and pulled the little rubber plug on the side of the liquid gauge and was able to dial in the pressure @ 5.5psi and noticed the liquid would gradually weep out when it warmed up under the hood. I do have the regulator and gauge mounted on the panel next to the radiator (not on the engine). The fuel pump still puts out 8psi so the regulator is needed. The carb is a 4160 (1850-12) 600cfm. Took it for a drive and works great now. I guess I was trying to adjust the regulator with a gauge that wasn't reading consistent.  Thanks again for the concern.  Dave V

How are you determining that the pressure drifts?  Engine  mounted gauges are not very reliable when the engine is warm and often indicate incorrectly.

Which Holley carburetor are you running?  There are a variety of needle seat assemblies for the model 4150/4160 4V carbs and the larger flow units are sensitive to higher than normal pressures.  While I haven’t had any problems with the factory mechanical pumps being too high on the fuel pressure, I do use the Holley fuel regulators with the electric fuel pumps without issue.

I'm having problems with too high of fuel pressure. I've purchased 2 different Y-block fuel pumps and one FE fuel pump. They all put out 7.5 to 8.5  psi which was causing the Holley carb to flood the engine. To try to correct the problem I've tried 3 different fuel pressure regulators which don't work. The last one was just installed a week ago and already went bad.  Unable to adjust (pressure drifts).  Anyone else having similar problem and what does it take to correct?  Dave V
