I am going to replace my mech fuel pump on my 350 chevy motor to an electric one. Since the motor has a 4 barrel carb I was wondering if anyone can suggest an electric fuel pump that will be reliable and also not be negatively affected by the addition of 10% - 15% ethanol. I have read and heard some bad things about the red holley electric fuel pump which I was considering. Any comments would be greatly appreciated. Thank you in advance for your help.
