George, the 20 years before I retired, I worked in the natural gas industry and from my experience a dozen low pressure gauges right out of the box would not yield more than two or three with the same reading.  I have a Mallory pressure regulator from Jegs, part # 650-4309 which the instructions stated it was set at 3 pds. for the Weber carb.  It is hooked to an auto gauge, but I haven't put the fuel in yet.  I guess if it doesn't overpower the float needle value, I'll just go with the reading that comes up on the gauge, unless there is a fuel starvation issue.  JohnD

Yvon,
Thanks Mate!  - it seems that most, if not all, Automotive fuel pressure gauges are inaccurate. I read Paul Yaw's write-up on them and it would seem Industrial pressure gauges 1- 5 PSI are best for Carb n/a applications.

Holley Performance Products offers both mechanical and 12 volts electric pressure gauges. I have been using the 0-16 psi electric gauge and sender for more than 5 years without problem. Yvon.

Chaps,
I'm looking for an Adjustable fuel pressure regulator for a carby (NA- low pressure)  with pressure gauge - any suggestions? I have looked at the Malpassi.
