Was the pump you installed a low pressure pump ( for a car with a small displacement engine and using a carburetor ) or a high pressure pump ( for a car with fuel injection ) ? What was the Airtex part number ? i'm just surprised you had a problem without the addition of the pressure regulator. So what is the output pressure of the pressure regulator ?

Just curious ......

It was one for a carburated engine.

I've used a regulator similar to this one

After some tweaking I ended up going back to 42 mph :)
