I have never run an electric fuel pump on any of my boats and have no knowledge on the requirement for fuel delivery and setup especially on my 455 Olds.
I will be running a 850DP Holley or 800CFM Edelbrock Marine. The Edelbrock I am still waiting on from the US.
1. I do not have fuel returns installed on my dual tanks, do I need to install returns?
2. What Psi pump do I use and Gallon P/H for fuel delivery.
3. Do I need a regulator?
4. Do I need a emergency cut off switch for the pump?
Thank you in advance.
