gas tank outlet too small? what size pump

[frankr]

The original gas tank on my 34 Dodge has a 5/16" outlet.
Will the 5/16" outlet be enough to feed the twin Edelbrock 600 cfm carbs on my 392 Hemi?
I will use an electric gas pump; what gpm do I need?
Will 7 lbs at the pressure regulator be OK?
RRR, Thanks for your help so far.

My opinion:

I'd much rather see a larger diameter tank outlet. If it were my car, I would change it with a new bung to at least 3/8" or -6AN. I have a 392 hemi, it's pretty thirsty. Seven pounds at the regulator outlet might be a tad high for those Edelbrock carbs but would work. I would try 6 or 6.5. Ony 90 GPH or above fuel pump should suffice.
