I now know that I have a 750 Holley Double Pumper carb on this car. It has a Mallory Electric Fuel pump and regulator. When I first got the car it ran about 8 psi on the gauge by the carb. I drove it up to a local shop to get the coolant flushed and filled and as we were running it the fuel pressure kept dropping. By the time I got it home it was about 2 1/2 to 3 psi. I had the alternator and batt tested while I was there - the batt was low on cranking amps and the alternator was not functioning properly. The car was still running and it started a little slow but it started. Is my fuel pressure problem due to low electricity or do I have another problem? The tank was brand new when the car was built so there shouldn't be any rust or junk coming from it. I'm going to take the alt off and have it tested again later this week.
