How much fuel pressure and volume does it take to fuel a 502 up to 550 HP? My boat is set up for an electric fuel pump and a I want to make sure I am set up correctly. Pump feeds a single Demon 850 carb. Also is the standard 454 mag water separator restrictive enough to affect the fuel pressure?
Thanks
Thanks

I don't have the dyno sheet in front of me but I think my 502 was 232 lbs/hr at 5800 rpm. 232 lbs/hr is about 35 gallons/hr. Fuel pressure is set at 6 psi. After problems with the non bypass pumps I switched to an Aeromotive marine pump with a bypass regulator. So far so good.

My 4 and 1/2 lbs seems to be on the short side as I thought.
