Whatever you do...If you decide to go with an electric pump go with a quality unit. I have run Holley pumps in the past with good results but some of the others aren't always a good idea if you want reliable transportation. Nothing like loosing fuel pressure at about 5000 miles from a worn pump. It happened to me once
I personally like mechanical pumps, that's me though. Others feel differently. There are many different regulators out there that can be plumbed in different configurations. Look around for one that works best for your situation & fuel line routing. Buy a decent pressure guage so you know the reading is accurate
