Aeromotive gen 2 stealth tank

Been looking at going EFI on 72 dart swinger with an la 360. Car is strictly for street. I have been leaning toward the holley sniper. I was looking at a tanks inc. in tank setup and came across this. It looks like a good setup. I like that it is assemblied and ready to go. I also like the fuel connections are suppose to be in stock location.

My question is how much pump capacity do I need? This one is 200lph. There is a 340 lph model. And does anyone know if this has for a vent? Any experience with this? I think it just become available.

It does look like it vents through the pump. The video shows a different top of pump versus the summit picture and it is vented in the video.
I have the Tanks Inc that I am running with the Holley sniper and it is vented through the pump and the tank also. I think you'd be fine with the 200lph pump, it should be more than enough for your 360.
