That certainly sounds like a fuel delivery issue.

4 psi is good on the pressure, maybe even a little high.

However, a good static pressure reading does not prove that fuel volume delivery is sufficient to meet on-the-road demand.


I think that adding a T connecton to monitor fuel pressure on the line between the pump and carburetor is a good idea, especially if you can locate the gauge where you can see it when you are driving the car.

Some variation in the fuel pressure might be expected, with some pressure drop when then engine is making more power, but it should not drop much and it should not stay down.

The fuel system is designed to be capable of delivering far more fuel than the engine can use.

Be sure all connections to the gauge, etc, are tight and secure, You do not want a fuel leak when the car is running.
