I also did the TanksInc set up, mine still has a carb, with a return system, EFI in the plans. hot fuel has not been a issue, & I drive this car, AC & temps over 100 deg in Southeast Texas.

You have any sump or baffling in there to prevent the pump from sucking air?
Yes there is a sump that comes with that pump. Very nice job there Andy. How did you handle the final finish? What is that?

I'm confused. Any good engine should have a brake specific horsepower number of around 0.5 lb/hp-hour. Assuming that an engine does more poorly than that at 0.7, at 600 hp that is 420 lb/hr of gasoline. At 6.07 lb/gal for gas, that is about 70 gal/hr. Why would you need fuel delivery rates over 100 gal/hr? What am I missing?

I would've bought a tank like that for my car but I couldn't find anyone who made one. I have a '65 Coronet and I did not have any luck finding a tank with a built in recess. Ideally I'd like to have a tank with the built in recess for the pump and have the tank be about 1 inch deeper. I think there is room in the early B body cars for a slightly deeper tank.
I might end up having a custom tank built for my car since I'd like it a bit deeper than stock but a little narrower so the 3 inch exhaust will clear. My leaf springs are moved under the frame so everything is a little tight back there. I can probably get someone to weld up a stainless tank for me if I draw up a blueprint. Hot Rod City Garage builds very nice custom EFI tanks, I used one of theirs on customers EFI 69 Charger.

It's not so much about what the pump flows.......its what the "system" flows, while maintaining the desired minimum pressure. Many fuel pump ratings are free flow......which doesn't really tell you anything useful.
