Hello, I have a 440 in the 64 Sport Fury in my avatar. Been running good for several years. Went to the Turkey Rod Run in Daytona. Car would misfire occasionally. Hit the gas, and it stalled. Pulled the 750 race Demon apart, cause I was getting a dribble out of the shooters. Put in a new needle and seat, reset float, and had to adjust the fuel pressure, as I have a Holley pressure regulator and gauge. Car drove fine on the trip home. When I looked at the gauge again, it was down to about 3.5 again. I put a different gauge on it, and it still read 3.5. Changed the regulator, and reset the pressure. it was putting out around 7.5 psi, which I thought was too high. The pressure kept falling back to 3.5 as the car ran longer. Tried to bring pressure back up, but it wouldn't. Also noted the fuel was lower in the sight glass. Smelled dipstick, no gas smell. I'm wondering if it's the pushrod is worn, and loses it's ability to move the fuel pump lever the proper amount when the engine warms up. Bear in mind, I've had this same setup on the car for over 10 years, with until now, no issues. Thanks.
