If I were to run a stock tank and EFI I would use the Holley Hyrdomat, its not cheap but proven to work.
I made a customed baffled sump for my stock tank and while I have never lost fuel pressure its crazy how much I can hear the pumps change tone with slosh on a low tank. I run two Walboro 255lph mounted just behind the tank, they are a few inches above the outlets on the tank and I am going to try going a little lower to see if it helps.
For the D150 tank we used an Aeromotive phantom fuel pump. Yes it was $380 or so, but it is very well designed. The plastic ring surrounding the foam with the return dumping into it makes a nice source for picking up fuel.
The D150 tank is very long, we will see how it performs at low fuel levels here soon, but I expect it to work quite well.
