Message: [QUOTE="Power Hungry, post: 287244, member: 1375"] Studded 7.3L with 250/200 FFD injectors, CPR fuel system, and stock Fuel Pump. [URL="http://www.youtube.com/watch?v=phR9EAgDZUI"]http://www.youtube.com/watch?v=phR9EAgDZUI[/URL] Fuel pressure regulator set at 68 PSI. As the run starts, you can see that the fuel pressure starts to fluctuate badly and by 2200-2400 RPM the needle drops to 25-28 PSI. Definitely not what we're looking for. Have two different fuel pumps coming tomorrow... the Walbro and a "stock" type fuel pump that supposedly flows more than stock. I don't have any specific numbers yet but the one advantage is that it is in the stock pump frame so it is a direct bolt-in replacement for the stock pump. We'll see what happens when the pumps arrive and I'll post new videos. [/QUOTE]
