Depends on the application. If the engine is relatively stock I would say a mechanical pump is the way to go. If your talkin' a high H.P. guzzler I would go for the electric fuel pump. I wouldn't want to take the chance of starving the engine @ high RPM = avoid the dreaded denotation.
Back in the days of stock car racin', we hooked up the mechanical fuel pump backwards. Used it to pump air into the fuel cell. Then ran 3/4" fuel line to the carbs. Kept about 6 lbs. constant pressure on the fuel line. Don't hold me to the 6 lbs. figure. That wuz' 35 years ago. It might have been 5.9 Lbs. He He HE.
We ran alcohol on that setup. Dirt Track, BBC. 72 Nova.
One night the Nova was invloved in an accident on the high bank curve. Me being the duty bound crew member that I wuz', ran out to the car to get the pressure off the tank A.S.A.P. so it we wouldn'r run the risk of dumping raw fuel in the engine. I spun the cap off the fuel cell not thinkin' it was on the curve. I got sprayed in the face with alcohol. Lemme tell ya' that wasn't fun. I ran across the track, with track personel in pursuit cuz' with alcohol you can't always see flames. Turned out there were no flames,(Lucky for me) but it took a while to catch my breath. Alcohol WILL take your breath away Fer' Shur". OOpppss Sorry, I get off track sum' times??/
