Priobe,
I had a similar problem way back. I had an Inglese 48IDA setup on a stroker small block. I have since changed alot of what Inglese originally setup because it did not work right.
Focusing on the gauge, mine was located at the end of the fuel line after the last carb. Engine cold and running fuel PSI was good. As engine heated up to fully warm fuel PSI would read 0 on the gauge (I even swapped out a couple different gauges). Engine still ran fine with no driveability problems. I ended up installing an Autometer electric fuel pressure gauge and mounted it inside the car. Never had a problem since.
Also the original Inglese setup had their push button diaphragm style regulator. I found this to be way to restrictive. I set my car up to run strong on the track but can drive in daily traffic all day long. The following is how I setup my car:
- fuel safe fuel cell
- holley low pressure fuel pump (blue)
- fuel curve west fuel regulator (this regulator can support a 2000 hp motor. It has a low pressure side I have set at 2.5 psi and a high pressure side I have set at 6 psi . There is an elctric solenoid built into this regulator that I have chipped into my MSD igniton box with an RPM activated switch so at a more elevated engine rpm range the regulator switches to the higher fuel psi where the engine is using more fuel.)
- return line back to fuel cell
- I designed and built my own phenolic spacer plate, 1/2" thick. This is a single plate that resides iabove the manifold and below all four carbs which provides three functions:
1) It provides a very nice thermal barrier preventing the fuel from boiling in the float bowls
2) Allows me to turn the passenger side carbs 180 degrees around so all four carb throttle plates open the same direction(fuel lines enter on drivers side of carbs.)
3) Enabled me to build my own linkage with a center mounted shaft mounted to two roller bearing pillow block assemblies that bolt to the phenoilc plate and run straight down the center of all four carbs(front to back). Each carb has it's own adjustable link to this shaft. This allows the deletion of the interconnecting linkage between the two carbs on each side, hence better carb synchronization.
This all may be more than you wanted to hear but my system is safe and works very well.

Goodluck.
