52 SBC EFI, gas tank help

[fireblade_rr]

Hello all,

1952 Chevy 3100 has a SBC 350 and Turbo 350 trans.
I'm thinking about installing a Edelbrock E-Street EFI system.
The truck already had a 19 gallon steel rear mount fuel tank installed.
Tank can be seen here http://www.lmctruck.com/features/ca/ca5s3.htm
Part # 32-5910

Does anyone know if or what in-tank fuel pump and sending unit I can use with this tank?
If there is no in-tank unit I can use my next question is how do I properly hookup a external inline pump? There are 2 outlets on the bottom corner (please see pic) and one on the top corner. Do I put the return next to the bottom outlet or do I install in on the top? Do I need a vent? Currently the top outlet is being used as a vent with a nipple and coiled up fuel line. I have a pop-up style cap (part # 32-5803 from same place the tank is from) and I'm not sure if its vented.
