Re: Electric Fuel Pumps...
As I remember the diameter of the fuel passage in the old blue Holley regulator is only .224. When I was doing some development work on the first annular 4500 hundreds the Holley engineers told us that the cross over for a second regulator was 580hp. The old blues were very smooth operating regulator’s.
