I would be more concerned with the pressure. The float needle will only stop so much.

An EFI fuel pump runs in a loop with the regulator keeping the pressure up to maybe 35psi. ANything past that is sent back to the tank. The pump is more than capable of supplying a carbureted engine, but can you control the pump? You need a regulator that sends the fuel back to the tank, which is no problem. Otherwise, use an engine mounted mechanical pump and don't poer up the tank pump. An engine doesn't need that much fuel. About .08 gallons per horsepower hour. A pump that could provide 16 GPH is adequate for an average 200hp smallblock. I don't keep track of that stuff anymore but I think the Holley electric is an 80GPH. Crazy. They want to take your money, of course, and sell you magnificently capable pumps. Something like a 30GPH mechanical will fuel anything you can think of. And face it, you use a lot of fuel for very short periods of time. The fuel bowls have enough fuel in them to spend 30 seconds at full power--you don't even need a pump capable of supplying maximum power full time. Your engine can't take maximum power fulltime.

Get a good mechanical pump and leave the electric in the tank unpowered is my suggestion.
