I currently have a 427 BBC putting out about 550hp at the flywheel. I would like to go with an electric fuel pump but maintain my stock gas tank. What should I do about the restrictive sending unit? If I put in a sump, it will be noticeable from the rear. Any suggestions? Right now the pump is mechanical but the lines are not very good looking so I am planning a complete fuel system overhaul. I have a single 950 Holley. Thanks all.
