Hello., I have a '72 that is almost all stock. I have been runny the Holley series carb (all chrome) on the 351c and the motor is running really rich. Anyway, eventually the carb starts dripping gas in the secondary bowls and it floods out the car. I have a high volume fuel-pump on the car and was wondering if I need some kind of adjustable fuel-pressure regulator and if I do where and what kind should I get? Or should I put on a regular fuel pump and try that? I have gone through three Holley carbs already. I am switching to an 600cfm Edlebrock (on order). Any ideas?

Mr.Guyman
You have had the identical problem for months. I don't believe you have a carb. problem, but rather a fuel supply problem. The high-volume fuel pump is probably putting out 12+ lbs of pressure.
Solutions either ,
1) put in a fuel pressure regulator. or;
2) put a standard fuel pump in.
Well... finally got around to changing the fuel pump to a stock one and I put on a new edlebrock carb with Manual choke. New fuel filter . I took it out today and it is running fabulously.,specially on the highway. Runs 90 mph with no effort at all. Seems to run kind of lumpy at idle at a light though. Not as rich as it was when first starting the car. I think I am still going to add a fuel pressure guage in the line so I know what psi it's running at. Thanks, guyman
