I like the return line fuel systems better. The Aeromotive 340 lph pump will work for you. They have a drop in tank unit available.

I have used stock modified for an in-tank pump, the Spectra tank and the one from Tanks Inc. I like the Tanks Inc. one the best. Is is well baffled, powder coated, has a good pump mounting setup and fits good. The Spectra tank works good also and is cheaper. The baffle setup is ok on the Spectra tank. I don't like the pump mounting setup they use and have had problems getting the lock ring gasket to seal. The main problem is the sender ohm range is not right and the fuel gauge is way off. I would use a Spectra tank before wasting time modding a stock one for the price and they also come with a good 255lph walbro pump.
The only Carbs I care about are under the hood!

I just put a new stock tank on my 73 Cuda before I considered the benefits of EFI. If EFI is in the budget next year, rather than replace or cut up the tank I'm going to try the Spectra pump assembly that goes in through the stock sender location. https://www.amazon.com/dp/B01N5B2I3D/?co...lv_ov_lig_dp_itProbably the same one in the tank RockAuto sells. If it works, it is the cheapest way I've seen to get an in tank fuel pump. I would think they would have one for the B body.

I have an Aeromotive 340 lph in a stock tank (Phantom system) in my Duster and it picks up fuel flawlessly. I would do a return line and also put a check valve in it.
I haven't plumbed my Russell check valve in yet, but the Aeromotive 340 LPH doesn't have a check valve as part of the pump like a normal EFI car so I get drainback and air in the rails if the car sits for more than a few days.
The return system will eliminate any possibility of vapor lock and keep your lines air free other than maybe the first 5-10 seconds the car runs.

Just a FYI on the Spectra EFI tank setup. Right now Autozone has a 20% off code and free shipping to your door until next Monday.
Just ordered one for my ride for ~$350 + tax.
Thanks for the suggestion on Spectra! That is a good price. I paid $366 back in 2015 for mine, and noticed the same place now wants $510 for them. Just check the wiring bulkhead to make sure the wires are not shorting, which me and at least another used had issues with. Just had to rotate the connection on the inside away from the support brace. Simple fix, but annoying to find after installing the tank and filling with fuel. For a ground, I used a sheet metal screw to connect a wire with a lug, in one of the outer tank corners where the top and bottom of the tank are seemed together (not into the fuel tank area of course.)

Spectra uses the same style sender as stock.
How does that sender work with a stock gauge? I've been through 4 replacement senders, that didn't work out of the box and all for different reasons, because I needed a 3/8" (I only paid for one). The one I have now works, but I don't think it is dampened in any way so it is only still when stopped or cruising. You jump on the gas and it drops at least 1/4 tank and then oscillates for a bit before stabilizing. It also seems to make fuel on cold mornings. By lunch time I usually have 1/4 tank more than when I started it that morning. Factory 5/16 sender works perfectly.
